Double Towel Racks – The Easy Way To Increase Space

Bathrooms almost always pose a storage challenge. They often have minimal space to do all the jobs we need to do in there and to store everything we use while we're in there.

When a bathroom is shared by a couple of people, or even an entire family, unique storage challenges come up, and they require unique solutions. When, say, four people use the same room for bathing, an obvious problem is: where do you put all the towels? Bathroom hardware manufacturers came up with a better solution: double towel racks.

A traditional single towel rack provides sufficient space to dry one towel. If you've got four people using four towels each day, and you have a typical bathroom, you'll need a wall covered with towel rods to provide enough drying space.

Double towel racks provide an innovation solution to this all-too-common bathroom storage problem. You'll find double towel racks come in traditional finishes like polished chrome and polished and antique brass, and popular finishes like brushed nickel and oil-rubbed bronze. You can find economic versions of double towel racks in unfinished wood and ceramic-and-plastic. Regardless of the amount the wall space you have available to install this hardware, you'll find one to fit your space; They come in the range of standard sizes.

If your bathroom is short on storage, you'll usually be open to considering any new space-saving solutions. You can find bathroom suites with a double towel racks installed below. Imagine-in the space where you could normally dry a towel or two, you can double your hanging space, and have room to store a few fresh folded towels and other bathroom essentials, too.

Double towel racks are an excellent solution when you've got lots of damp towels to handle, but other solutions do exist:

• Install a row of pegs or hooks along the wall of the bathroom.
• Install one or more multi-prong hooks on the back of the bathroom door.
• Buy a shower curtain rod with a towel rack incorporated in its design.
• When you purchase shower doors, look for ones where the handles double as towel bars.
• Install suction-cup hooks inside the tub surround.
• Place a swing-arm towel bar to the wall next to your tub or shower. This way, the towel bars extend into the room; They are not limited to hanging against a wall.
• Hang a hook over the bathroom door, linen closet door, or the door of the water closet. These over-door hooks come in single, double, and multiple hook versions in colors and finishes that either stand out or blend in.
• Repurpose an old-style coat rack and use it to hang towels in the bathroom. It takes up only a single square foot of precious floor space.
• If you want to add furniture to your bathroom, look for a hall tree, which is usually reserved for use in the foyer or a mudroom. They come in many styles and finishes, equipped with hooks, mirrors, storage benches, and shelves.
• If you've fortified enough to have a sizable linen closet in your bathroom, visit the closet organization section of your home improvement store. These stores have trained personnel who can help you look at the space you have and redesign it to suit your needs.

Installing a couple of double towel racks can provide a simple way to add storage space to your bathroom. But investigate all the possible storage options for your unique bathroom design challenges. You're not limited to one solution-think creatively and combine them to make a bathroom that works for you.

What Is The Difference Between ERP And Enterprise System?

Enterprise system and Enterprise Resource Planning System terms are similar but there is difference between an enterprise system and an ERP system. An ES or enterprise system is a large scale system which includes packages like ERP and CRM. ERP is a subset of Enterprise System or it can be said that ES is a superset of ERP. It contains a variety of solutions. ES contains applications and packaged solutions which can be directly used in an enterprise. On the other hand ERP system is the automation of the business processes and the solutions are in the form of modules which are designed according to the client’s requirements.

The functions are customized according to the client’s business environment. Enterprise system does not include architecture of other solutions whereas an ERP implementation automates systems using technical aspects. ERP system includes architectures and databases and is client server architecture. The system is server based therefore the consultant needs to be aware of the technical aspect too.

Another difference between an ES and an ERP system is that the ERP is aimed at improving the functionalities of the organization whereas the ES helps to improve the overall maintenance and accuracy. It provides for better solutions and aids in decision making. ES is difficult to implement compared to Enterprise resource planning and even the timeframe needed for implementation maybe more. The overall impact is high but so are the risks involved. If the ES is not implemented in the right manner, it can cause business failure and if implemented properly it can increase the efficiency and profits of the business organization. It is normally required when there is a big drawback in the current procedures and methodologies in the organization and need to be corrected. The company going in for enterprise system needs to be careful while choosing the software and the vendors due to the risk of failure involved.

The difference between an enterprise system and an ERP system is that ERP is mostly used for medium scale companies to big companies and ES is restricted to the big companies. There are many complex functions involved in big companies which cannot be provided solutions for alone by ERP. The role of ERP is restricted when compared to enterprise system because it does not include customer relationship or vendor management.

These applications are needed when the business process is complex and on a big scale. Therefore bigger organizations need to go with ES instead of enterprise resource planning alone. ERP is also an important system to streamline the internal processes but it does not provide for taking care of the external processes. Enterprise system takes care of the end to end business process of organization since it involves other applications also like SCM and CRM. There is quite a lot of difference between an enterprise system and an ERP and it depends on the company whether it wants to go with an ES to streamline the entire process starting from supplying, production and customer or whether he wants to go with an ERP system to streamline the internal process.

Medical Coding History – From Paper to Medial Coding Software

If we define medical coding as the assignment of alphanumerical characters to diagnoses, diseases, and treatments, then medical coding has been traced back to the 1600s in England with the London Bills of Mortality. A more standardized system of coding was developed for classifying death at the tail end of the 19th century. In 1893, Jacque Bertillon, a statistician, created the Bertillon Classification of Causes of Death, a system which was eventually adopted by 26 countries at the beginning of the 20th century. Shortly after the Bertillon Classification system was implemented, people began discussing the possibility of expanding the system beyond mortality as a way of tracking diseases.

By the middle of the 20th century, the World Health Organization (WHO) adopted a goal of a single global classification system for disease and mortality, entitled the International Classification of Diseases, Injuries, and Causes of Death (ICD). This classification system is updated every 10 years. The latest revision, ICD-10, is scheduled for adoption in the United States in 2013.

What started out as a small set of medical codes has evolved into a complex system that was initially standardized by the American Medical Association back in 1966 with current procedure codes (CPT) codes that are updated annually.

In the late 1970s, the Healthcare Common Procedure Coding System (HCPCS) was developed based on CPT. HCPCS has three levels of codes: Level One is the original CPT system. Level Two codes are alphanumeric and include non-physician services such as ambulances and other transportation as well as patient devices such as prosthetic devices. Level Three codes were developed as local codes, and were discontinued in 2003 in order to keep all codes relevant worldwide.

Recently, medical coding systems have been expanded to include other medical specialties. For example, there are coding systems related to disabilities, the dental field, prescription drugs, and mental health.

As the coding systems have become more complex and diverse, the need for training of medical coders has grown exponentially. Private training schools and public colleges throughout the country have developed certification programs. In order to be awarded a certificate, students must obtain a two-year degree from an accredited medical coding school and pass an exam given by the AHIMA.

Over the past 20 years, many coding processes have shifted from a paper-based system to a computer-based system using medical coding software and medical billing software. Many companies sell complete medical software-based coding solutions and myriad of products for specific medical disciplines, such as products that are specifically tailored to skilled nursing facilities, physicians, hospitals, surgery, cardiology, and more.

As medical facilities and professionals begin preparing for the conversion to ICD-10 in 2013, the need for more sophisticated medical coding software solutions and qualified medical coders will continue to grow.

CPT is a registered trademark of the American Medical Association.

How to Resolve “Memory Card Error” From Canon IXUS 130

Canon IXUS 130 is a sophisticated digital camera that has a resolution of 14.1 megapixels. The camera is inbuilt with almost all advanced features, including fully wide-angle 4x zoom lens and motion blur technology. The IXUS camera is compatible with SDHC (Secure Digital High Capacity) and SDXC (Secure Digital Extreme Capacity) cards, with storage capacity as high as 2TB.

Since the storage memory of the cards is huge, data loss from these cards is simultaneously huge. One of the main reasons for data loss from cards is corruption of these cards. In most cases, you receive an error message after your card gets corrupted. However, an updated backup allows you to overcome card corruption. It allows you to restore data. But in case of unavailability of backup, you can use recovery software to recover data from a corrupted card.

As a practical case, you view the below error message on Canon IXUS 130 while attempting to view some previously stored photos on your SDHC card:

“Memory Card Error”

Every single photo saved in the memory card becomes inaccessible after the above error message appears. In addition, no more photo can be saved on card. In short, the card can not be read or written upon.

Cause:

The above error message that makes all the photos inaccessible is primarily caused due to corruption of card. Few reasons that are accountable for the above error message are virus infection, interrupted read/write operation, and human errors.

Resolution:

The resolution for the above error message is formatting of memory card in the camera itself. The process deletes all the previously saved data and allows you to save new data. While formatting proves a good resolution for users who do not require the old data, it becomes fatal for users, like photographers, detective agents, etc, who save critical data in their memory card. However, recovering formatted data now-a-days is an easy process. To do so, you need to use an advanced third-party Photo Recovery Software. A Image Recovery tool is readily available on the Internet by just one single click.

What is the Purpose of ERP Software?

Enterprise Resource Planning (ERP) software can be described as a complete business software solution. It is aimed at the integration of all business processes and sub-processes into a single unified system. This system is formulated and implemented in an organization to effectively and efficiently achieve the business goals of the organization.

ERP packages are implemented to manage the existing and prospective business plans and policies in an efficient manner under strict deadlines. It can be referred to as the ultimate business solution package that is predominantly concerned with making sure that the available resources of the organization are utilized in the best possible manner and coordinated with the business objectives of the organization.

It is crucial that modern day business organizations have a single unified system, which aims at harmonizing its business efforts. This can prove to be a crucial determinant in deciding the scope, area and net results of the organization as a whole, rather than running many different systems that don’t work well together. What makes ERP different from any other business solution package is the presence of a single and unified database system.

ERP software is as essential to the needs of a business today as food is for living. Businesses cannot run competitively in the absence of properly drafted and formulated ERP software. The more effective implementation and follow-up, the better are the results. ERP software is needed by all modern-day organizations, irrespective of the size, area of operations and business objectives.

Nowadays there are many ERP packages available in the global market, including SAP, PeopleSoft, Oracle, J D Edwards, and BAAN.

The selection of an ERP software package is dependent on many factors: previous software implementation, nature and size of operations, recommendations of consultants, and management decisions.

Before installing specialized software, a detailed study must be made and reviewed to match the business requirements with the available packages. This must be taken as a serious study as any mistake in selection or its effective implementation can prove disastrous to the organizational objectives and prospects. The ERP software must be installed by an ERP vendor or third-party consulting organization, which are expert service providers when it comes to providing Consulting, customization and support.

Some of the benefits of ERP Software:

* All processes and sub-processes are linked and unified into a single system.

* There are enhancements in the field of productivity, efficiency and achievement of business objectives.

* ERP tends to considerably reduce the response time by effectively transferring crucial information.

* ERP helps in streamlining the numerous functions performed by the organization as a whole.

* It helps the management to make vital decisions with unparalleled accuracy and in-depth study.

Thus, ERP software can effectively change the outlook of any business organization that exists in today’s cutthroat business world. Proper implementation of the ERP software is the key factor, which can benefit the growth prospects of any organization.

10 Top Reasons Why I Have to Upgrade My Computer

The rate at which technology is improving is very fast and in the time you get comfortable with the computer hardware you have bought, several new and improved models appear in the market. While some people prefer to keep their computers state of the art, most of us have a 'If it is not broken, do not fix it' attitude when it comes to upgrading or replacing our computers.

This is a strategy that could prove expensive in the long run. It is always better to upgrade your computer on a regular basis, especially if you have had it for over 2-3 years. Even if your computer has had a large trouble-free existence, you really need to consider periodic upgrades and here are the reasons why you must dos so:

1. Increase in Processing Speed ​​- This is one place where you really get to notice an improvement in performance. If you are upgrading from a Celeron 433MHz processor to a Pentium 4 1.6GHz, you would really notice the difference in performance!

2. Faster Memory Access – Improvements in CPU speed are typically accommodated by improvements in the speed at which data transfer occurs between the CPU and RAM. This is another area that provides an improvement in performance.

3. Size and Capacity improvements – Technology drives a reduction in component size coupled with an increase in storage capacity. This means that a RAM card or hard disk of the similar size as the older ones in your computer could have double the capacity!

4. Software Compatibility – Many of the new software packages you may wish to use in order to improve your productivity or entertainment experience may not function well on you old computer. It is better to upgrade your computer to enjoy the benefits of new software fully.

5. Obsolescence of Hardware – As your hardware gets older; Getting a replacement will get more difficult once manufacturers start phasing out the production. With improvement in technology, the older hardware becomes cheaper initially and becomes expensive as supply dries up.

6. Technical Support Issues – Many manufacturers stop providing technical support for older components as they cease production. The older your computer gets, the harder it is to find help in fixing it when it malfunctions.

7. Development of New Hardware – New hardware products appear in the market frequently that revolutionize your computer experience and are based on newly developed technology. The chances of your old computer supporting new devices are very low.

8. Faster Devices – Your old computer may not be in a position to accommodate the speed at which the new devices communicate.

9. New, Fast Communication Protocols – You may not be able to implement new or faster communication protocols in your old computer because the hardware is unable to support them.

10. Operating System and File Format – Your old hardware may not be able to run newer operating systems and some of the file formats may not be supported.

Choosing the Right SDLC For Your Project

Choosing the right SDLC (Software Development Lifecycle) methodology for your project is as important to the success of the project as the implementation of any project management best practices. Choose the wrong software methodology and you will add time to the development cycle. Adding extra time to the development cycle will increase your budget and very likely prevent you from delivering the project on time.

Choosing the wrong methodology can also hamper your effective management of the project and may also interfere with the delivery of some of the project’s goals and objectives. Software development methodologies are another tool in the development shop’s tool inventory, much like your project management best practices are tools in your project manager’s tool kit. You wouldn’t choose a chainsaw to finish the edges on your kitchen cabinet doors because you know you wouldn’t get the results you want. Choose your software methodology carefully to avoid spoiling your project results.

I realize that not every project manager can choose the software methodology they will use on every project. Your organization may have invested heavily in the software methodology and supporting tools used to develop their software. There’s not much you can do in this case. Your organization won’t look favorably on a request to cast aside a methodology and tools they’ve spent thousands of dollars on because you recommend a different methodology for your project. We’ll give you some tips on how to tailor some of the methodologies to better fit with your project requirements later in this article. In the meantime, before your organization invests in software development methodologies you, or your PMO, ought to be consulted so that at least a majority of projects are benefited from a good fit.

This article won’t cover every SDLC out there but we will attempt to cover the most popular ones.

Scrum

Scrum is a name rather than an acronym (which is why I haven’t capitalized the letters), although some users have created acronyms, and is commonly used together with agile software development. Scrum is typically chosen because of its iterative nature and its ability to deliver working software quickly. It is chosen to develop new products for those reasons. There is typically no role for a project manager in this methodology, the 3 key roles are: the scrum master (replacing the project manager), the product owner, and the team who design and build the system. There is only one role that you would be asked to play if your organization is committed to using this methodology, scrum master. If you should determine that this would actually be the best methodology for your project, you’ll have to re-examine your role as project manager. You can either identify a suitable scrum master and return to the bench, or fill the role of scrum master.

Scrum suits software development projects where its important for the project to deliver working software quickly. Scrum is an iterative methodology and uses cycles called sprints, to build a working system. Requirements are captured in a “backlog” and a set of requirements is chosen with the help of the product manager. Requirements are chosen based on 2 criteria: the requirement takes priority over others left in the backlog and the set of requirements chosen will build a functioning system.

During the sprint, which can last from 2 to 4 weeks maximum, no changes can be made to the requirements in the sprint. This is one of the reasons that a project manager isn’t necessary for this methodology. There is no need for requirements management because no changes are allowed to the requirements under development. All changes must occur in the requirements set in the backlog.

Scrum will be suitable for software development projects where the product is a new software product. By new I mean that it is new to the organization undertaking the project, not in general. The methodology was developed to address a need for a method to build software when its necessary to learn on the fly, not all requirements are known to the organization and the focus is on delivering a working prototype quickly to demonstrate capabilities. You need to be careful when choosing requirements to deliver in each sprint to ensure that the set developed builds a software system that is capable of demonstrating the feature set supporting the requirements included.

You also need to ensure that these requirements are well known and understood as no changes are allowed once the sprint starts. This means that any changes to the requirements must come through a new set of requirements in the backlog making changes to these requirements very expensive.

This methodology divides stakeholders into 2 groups: pigs and chickens. The inventors of this methodology chose this analogy based on the story of the pig and the chicken – it goes something like this. A pig and a chicken were walking down the road one morning and happened to notice some poor children who looked like they hadn’t eaten for days. The compassionate chicken said to the pig: “Why don’t we make those children a breakfast of ham and eggs?” The pig said: “I’m not happy with your suggestion. You’re just involved in making the breakfast, I’m totally committed!” The point to this is the product owner, scrum master, and team are all in the “pig” group. All others are in the “chicken” group. You will be in the “chicken” group if you choose the Scrum methodology as a project manager.

Waterfall

Waterfall methodology calls for each phase of the development cycle to be repeated once only. Requirements will be gathered and translated into functional specifications once, functional specifications will be translated to design once, designs will be built into software components once and the components will be tested once. The advantage of this methodology is its focus. You can concentrate the effort of all your analysts on producing functional specifications during one period rather than have the effort dispersed throughout the entire project. Focusing your resources in this way also reduces the window during which resources will be required. Programmers will not be engaged until all the functional specifications have been written and approved.

The disadvantage of this approach is its inability to teach the project team anything during the project. A key difference between the waterfall approach and an iterative methodology, such as Scrum or RUP, is the opportunity to learn lessons from the current iteration which will improve the team’s effectiveness with the next iteration. The waterfall methodology is an ideal methodology to use when the project team has built software systems very similar to the one your project is to deliver and has nothing to learn from development that would improve their performance. A good example of a project which would benefit from the waterfall methodology is a project to add functionality to a system the project team built in the not too distant past. Another example of an environment that is well suited to the waterfall methodology is a program to maintain a software system where a project is scheduled for specific periods to enhance the system. For example, an order and configuration software system which is enhanced every 4 months.

The waterfall methodology does not lend itself particularly well to projects where the requirements are not clearly understood at the outset. Iterative approaches allow the product owners or user community to examine the result of building a sub-set of requirements. Exercising the sub-set of requirements in the iteration’s build may cause the product owners or user community to re-examine those requirements or requirements to be built. You won’t have that opportunity with the waterfall method so you need to be certain of your requirements before you begin the build phase. Interpreting requirements into functionality is not the only aspect of development that can benefit from an iterative approach. Designing the system and building it can also benefit from doing these activities iteratively. You should use the waterfall method when your team is familiar with the system being developed and the tools used to develop it. You should avoid using it when developing a system for the first time or using a completely new set of tools to develop the system.

RUP

The Rational Unified Process, or RUP, combines an iterative approach with use cases to govern system development. RUP is a methodology supported by IBM and IBM provides tools (e.g. Rational Rose) that support the methodology. RUP divides the project into 4 phases:

1. Inception phase – produces requirements, business case, and high level use cases

2.Elaboration phase – produces refined use cases, architecture, a refined risk list, a refined business case, and a project plan

3. Construction phase – produces the system

4. Transition phase – transitions the system from development to production

RUP also defines 9 disciplines: 6 engineering disciplines, and 3 supporting disciplines: Configuration and Change Management, Project Management, and environment so is intended to work hand in hand with project management best practices.

Iteration is not limited to a specific project phase – it may even be used to govern the inception phase, but is most applicable to the construction phase. The project manager is responsible for an overall project plan which defines the deliverables for each phase, and a detailed iteration plan which manages the deliverables and tasks belonging to each phase. The purpose of the iterations is to better identify risks and mitigate them.

RUP is essentially a cross between Scrum and waterfall in that it only applies an iterative approach to project phases where the most benefit can be derived from it. RUP also emphasizes the architecture of the system being built. The strengths of RUP are its adaptability to different types of projects. You could simulate some of the aspects of a Scrum method by making all 4 phases iterative, or you could simulate the waterfall method by choosing to avoid iterations altogether. RUP will be especially useful to you when you have some familiarity with the technology but need the help of Use Cases to help clarify your requirements. Use Cases can be combined with storyboarding when you are developing a software system with a user interface to simulate the interaction between the user and the system. Avoid using RUP where your team is very familiar with the technology and the system being developed and your product owners and users don’t need use cases to help clarify their requirements.

RUP is one of those methodologies that your organization is very likely to have invested heavily in. If that’s your situation, you probably don’t have the authority to select another methodology but you can tailor RUP to suit your project. Use iterations to eliminate risks and unknowns that stem from your team’s unfamiliarity with the technology or the system, or eliminate iterations where you would otherwise use the waterfall method.

JAD

Joint Application Development, or JAD, is another methodology developed by IBM. It’s main focus is on the capture and interpretation of requirements but can be used to manage that phase in other methodologies such as waterfall. JAD gathers participants in a room to articulate and clarify requirements for the system. The project manager is required for the workshop to provide background information on the project’s goals, objectives, and system requirements. The workshop also requires a facilitator, a scribe to capture requirements, participants who contribute requirements, and members of the development team whose purpose is to observe.

JAD can be used to quickly clarify and refine requirements because all the players are gathered in one room. Your developers can avert misunderstandings or ambiguities in requirements by questioning the participants. This method can be used with just about any software methodology. Avoid using it where the organization’s needs are not clearly understood or on large, complex projects.

RAD

RAD is an acronym for Rapid Application Development uses an iterative approach and prototyping to speed application development. Prototyping begins by building the data models and business process models that will define the software application. The prototypes are used to verify and refine the business and data models in an iterative cycle until a data model and software design are refined enough to begin construction.

The purpose of RAD is to enable development teams to create and deploy software systems in a relatively short period of time. It does this in part by replacing the traditional methods of requirements gathering, analysis, and design with prototyping and modeling, the prototyping and modeling allow the team to prove the application components faster than traditional methods such as waterfall. The advantage of this method is it facilitates rapid development by eliminating design overhead. It’s disadvantage is that in eliminating design overhead it also eliminates much of the safety net which prevents requirements from being improperly interpreted or missed altogether.

RAD is suitable for projects where the requirements are fairly well known in advance and the data is either an industry or business standard, or already in existence in the organization. It is also suitable for a small development team, or a project where the system can be broken down into individual applications that require small teams. RAD is not suitable for large, complex projects or projects where the requirements are not well understood.

LSD

Lean Software Development, or LSD, applies the principles of waste reduction from the manufacturing world to the business of developing software. The goal of LSD is to produce software in 1/3 the time, on 1/3 the budget, and with 1/3 the defects of comparable methods. Lean does this by applying 7 principles to the endeavor of software development:

1. Eliminate waste

2. Amplify Learning (both technical and business)

3. Decide on requirements as late as possible

4. Deliver as fast as possible

5. Empower the team

6. Build integrity

7. See the whole

Although Lean Manufacturing has been around for some time, its application to the process of developing software is relatively new so I wouldn’t call it a mature process.

LSD would be a suitable method to use where you have a subject matter expert in the method who has some practical experience in applying lean methods to a software development project. “Amplified” learning implies that your development team has a depth of knowledge in the software tools provided, and also a breadth of knowledge that includes an understanding of the business needs of the client. LSD would be suitable for a project where the development team has these attributes.

LSD depends on a quick turnaround and the late finalization of requirements to eliminate the majority of change requests, so will not be suitable for a project where a delayed finalization of requirements will have a poor chance of eliminating change requests, or the size and complexity of the system being developed would prevent a quick turnaround.

Extreme Programming (XP)

Extreme programming places emphasis on an ability to accommodate changes to requirements throughout the development cycle and testing so that the code produced is of a high degree of quality and has a low failure rate in the field. XP requires the developers to write concise, clear, and simple code to solve problems. This code is then thoroughly tested by unit tests to ensure that the code works exactly as the programmer intends and acceptance tests to ensure that the code meets the customer’s needs. These tests are accumulated so that all new code passes through them and the chances for a failure in the field are reduced.

XP requires the development team to listen carefully to the needs and requirements of the customer. Ambiguities will be clarified by asking questions and providing feedback to the customer which clarifies the requirements. This ability implies a certain degree of familiarity with the customer’s business; the team will be less likely to understand the customer’s needs if they don’t understand their business.

The intent of XP is to enhance coding, testing, and listening to the point where there is less dependency on design. At some point it is expected that the system will become sufficiently complex so that it needs a design. The intent of the design is not to ensure that the coding will be tight, but that the various components will fit together and function smoothly.

XP would be a suitable software development method where the development team is knowledgeable about the customers business and have the tools to conduct the level of testing required for this method. Tools would include automated unit testing and reporting tools, issue capture and tracking tools, and multiple test platforms. Developers who are also business analysts and can translate a requirement directly to code are a necessity because design is more architectural than detail. This skill is also required as developers implement changes directly into the software.

XP won’t be suitable where the development team does not possess business analysis experience and where testing is done by a quality assurance team rather than by the development team. The method can work for large complex projects as well as simple smaller ones.

There is no law that states you must choose one or the other of these methodologies for your software project. The list I’ve given you here is not a totally comprehensive list and some methodologies don’t appear on it (e.g. Agile) so if you feel that there is some other methodology that will better suit your project, run with it. You should also look at combining some of the features of each of these methods to custom make a methodology for your project. For example, the desire to eliminate waste from the process of developing software is applicable to any method you choose and there is likely waste that could be eliminated in any development shop.

Be careful to choose a methodology that is a good fit for your team, stakeholders, and customer as well as your project. Bringing in a new development methodology that your team will struggle to learn at the same time they are trying to meet tight deadlines is not a good idea. On the other hand, if you have the latitude you may want to begin learning a new method with your project.
