Buggy software costs economy billions of dollars world wide! We believe the best way to develop a software is understanding the needs of all the stakeholders and having the right mix of people involved in the entire application life cycle. Small changes like have the QA team involved in the early planning stages, soliciting inputs from business analysts and automating more of the testing phase enable the company to meet or exceed its goals of a successful deployment i.e. application availability and overall user satisfaction with the application. Using the Application Life cycle Management (ALM) model meets the basic goals of application development. They include ensuring adequate communication between the teams responsible for each stage and preventing errors from progressing through the cycle, since its costs more to fix errors later in the development process than at the beginning. The life cycle appears obvious, but has been extremely difficult to implement in most corporations. We have inculcated this important idea in our training programs to avoid the known pitfalls that exist in the developmental cycles at most companies.
Quality From the Start
Establishing clear communication channels among developers, testers and the business users is critical to successful life-cycle management. This needs to be made part of the process during the planning stage.
Testing and More Test
While developers do some early testing as they go, a full blown testing process is crucial to finding and fixing bugs. After the developer passes off the code, it is subjected to thorough checks, including functional testing to evaluate the flow and functional correctly of the program, integration testing, performance testing, security testing and regressing testing of updates and changes to the program.
Closing the Loop
Once deployed an application must be monitored and maintained. All updates to the software will begin a fresh application lifecycle, so information collected during production must be fed back to the requirements planning of the next rendition.
