7 Step SDLC Process for Custom Application Development

We are used to follow predefined processes to ensure that whatever we do is perfect in all aspects and benefits us immensely. custom application development a highly competitive field is also not free from a predefined process which ensures that the software developed is developed and deployed as per the standard practices. SDLC stands for Software Development Life Cycle and lays down a step by step process to software development using different platforms like PHP, asp.Net, Flex, Silverlight, SharePoint, BizTalk etc.

Various models of SDLC exist, which model should be used for the custom application development project of an offshore software development company depends on the type of project and other details. Whichever process is selected the 7 basic steps for custom application development using SDLC remain the same. Here we have listed them for your understanding:

Planning:

What is software? It is a concept coded into an application to help companies ease their business processes. To transfer the concept into an application requires lot of planning as it involves lot of work and money. Planning begins once the feasibility of the software is assessed.

Design:

This step should not be mixed with designing the look and feel of the application as it relates to deciding the specifics of the application like which platform will be used and how the custom application development will be done. It is in fact a rough plan which depicts almost all the stages involved in custom software development. Project managers and designers collaboratively design the software.

Implementation:

Then comes the time to put into practice all decisions made. The first step to begin with is to develop a plan and get it approved from the stakeholders. While this is a general process for custom application development there are many offshore software development companies which believe in following the iterative SDLC process by which software development is done slowly and steadily taking client approval at each stage.

Testing:

Two main types of testing are used a) tested by users and b) professional testing. The first type of testing is useful when the application is directly deployed to the end users. Second type of testing is done in offshore software development companies where it is important to clean the application of all the bugs before delivering it to clients.

Acceptance:

This term refers to the acceptance of the software in place of the old one which is depicted through the number of people using it. It can be accepted as a new tool or a tool in place of an old tool.

Maintenance:

Once the software is developed it is never good as it is. Often changes are asked for in the existing product, maintenance of the application refers to that part where changes to the applications are made on an as needed bases. Offshore software development companies have to provide maintenance support through phone, chat or email. Product upgrade is also included as part of the service.

Disposal:

Everything that becomes obsolete needs to be disposed and similar is the case with custom software. Disposal is the last step involved in the SDLC methodology for custom application development. It is not as easy as it sounds because disposal here means complete disposal of the application so that no history of records is ever found.
