Software Development Life Cycle – Basic Steps Leading to A Strong Product

After realizing and experiencing the alluring advantages of outsourcing, more and more companies are getting inclined towards outsourcing software development projects to major offshore destinations. However, having an in-depth knowledge of software development life cycle becomes a priority task for not only the service provider software development company but also the client to keep a check on the project progress throughout the software development.

Software development is an intricate process that requires a lot of planning, implementation and testing. You can not develop perfect software with full functionality unless it passes all the tests and quality analysis. So, companies should keep a check on SDLC while experiencing software development outsourcing, a company No software is perfect and in full functionality unless it overcomes all the tests.

A software development company put special emphasis on SDLC to produce the most effective, functional and mission critical software that can help one’s business in a long run. The software development life cycle (SDLC) is a pre-set framework that is used by all software development companies for through understanding and developing effective information systems and software.

Though software development life cycle can have many versions and each version carries its own plus points and minus points, but all version have same steps or activities that are discussed below;.

Feasibility

First of all, the project is checked for its feasibility if it should get the go-ahead. If the project is to proceed, then a project plan is thought out together with the budget estimates for future stages of development.

Requirement Analysis and Design

After testing the feasibility of the project, system or software requirements are gathered. Business analysts perform a thorough study and analysis of the business needs of the organization and the market trends. Necessary changes are proposed. From interface design to data design, every program is discussed in this stage to keep the software of high level design.

This phase considers the overall structure of the software and defines the strategy for its development. That’s requirement analysis and design phase is believed to be the most critical part of software development life cycle. Any flaw in this phase may prove very expensive for further stages of life cycle. In simple words, this phase considers the logical system of the product.

Code generation and Implementation

This phase involves the code translation of the well-thought design. Desired programs are created using a conventional programming language and with the help of programming tools like Compilers, Interpreters, Debuggers. The code is generated using various high level programming languages like C, C++, Pascal, Java, etc.

Testing and Quality Assurance

Apart from requirement analysis, testing is another crucial stage of SDLC that decides the effectiveness and functionality of the product. This phase unravels the bugs and errors of the system. Initially the individual modules of programs are tested separately which is followed by testing of the system as a whole. The system testing includes the integration testing to check whether the interfaces between modules are working properly, Volume testing to ensure the capability of the system to work on an intended platform with the expected load of data, and acceptance testing to check whether the system does what the user needs.

Maintenance and Support

Software system maintenance is an inevitable need. It undergoes various changes once it is delivered to the client. Software development should be flexible enough to inculcate required changes with time and according to changing business needs. Inevitably the system will need maintenance. Software may undergo certain changes once it is delivered to the customer. There are many reasons for the change. Change could happen because of some unexpected input values into the system. In addition, the changes in the system could directly affect the software operations. Therefore, the software should be developed in order to accommodate changes that could happen during the post implementation period.

Each and every stage of SDLC carries its own importance and plays a key role in success of any software development project.

Top Five Software Developments

A company’s website is the main point of contact with its customers and so needs to act as a source of information, a social gathering point, a shop and publicity machine all in one. Most companies have a host of software programs running behind the scenes making everything appear to run smoothly and seamlessly from accounts to document storage. Computers have revolutionized business for companies and the software development companies that produce systems to keep work on track are central to this process.

This free, simple system will have you writing about your business within minutes and keeping the world in touch with your progress.

3. Virtual Conference

4. Document Sharing
It is common for companies to use standard documents and templates for business and it is important that all staff have the ability to access information at any one time. Software developers at Google have come up with a useful documents tool that allows personnel to work from the same documents and access group information simultaneously.

5. Sales Co-ordination

Everyone benefits from keeping tabs on their client base, sales and salesforce activities.

Crucial Stages of Application Software Development

Any software is created by several methodologies and programming codes put together. Application software gives life to the machines. But while making use of electrical equipment, we never think much about its internal working process. The software available these days are of two major types.

1. System software: The system software has been designed in a way in which it offers a common interface between the person who is using it and the hardware of the system.

2. Application Software: The application software is programmed in such a way that it is capable enough to assist the person in multi tasking. It assists in bringing solution to different problems, helps to customize ‘n’ number of graphics, texts as well as numbers.

Various types of application software are available in the market including entertainment software, infrastructure software, content management software and many more. There are specifically defined stages for the development of application software. The process of it is mentioned below.

  • Defining the requirement: During this stage, the authorities of the company define the requirements of the client and plan out the design so that the product can be made accordingly. During this stage the budget and the deadlines of the project are also decided.
  • Designing: The designing part is the heart and soul of any software. This is because the smooth working of the software depends on the quality of the design. The software is usually created and developed by the software developers based on the plan which is accepted by the client as well as the organization. There are times when the company hired for the software development fails to integrate the features that have been asked for. In these cases they have to invest in debugging.
  • Testing the software: Testing is important to ensure that the system works smoothly and the programs developed are capable and efficient of working in any situation. During the testing process, the testers manipulate the programs to check if there are any loopholes.
  • Putting the software into practice: When the application software development is done and it is void of any flaws, it is put into practice by the client. Even during this stage, if there are any errors in the system, they can be checked and corrected.
  • Servicing: The firm providing application and software development should also be ready to provide regular servicing and maintenance to the clients whenever necessary. Customer support should also be provided by the hired firm so that the client queries and doubts can be cleared.
