ISTQB - Software Development Models

In last article we have seen about the software development life cycle and in this article we will deeply understand about the software development models. Software development life cycle will you the process of execution while developing a product but software development models will give you the actual idea about which methodology you can use for your product. For example, A merchant have an idea that he wants to prepare a chair but He will start to build with the sitting area first or He will start with the legs first that will be define as per he decide to follow the models of different chairs.

Thus, basically software development models have different kind of process and methodologies which can be selected as per the requirement of product or application. So many models are available for software development life cycle which have different objectives to follow. As the project’s goal, we need to select one model for same. The models are define with the stages of development which we needs to follow.

ISTQB - Software Development Life Cycle (SDLC) Part 2

In last article we have seen about software development life cycle and understood its 3 level. In this article we will continue with the level 4, 5 & 6 of SDLC. 

4. Testing:

Software testing is came in the 4th level of software development life cycle. As we have seen tester can be involved in first phase of software testing life cycle. This is very important point, as we are taking tester team members in the requirement gathering then most of discussion will be done in front of all the teammates so communication gap will not be there during the project development phase.

Even needed improvements and suggestions can be noted down in the requirement gathering phase. As we know that after requirement gathering next phase is design and then coding phase came to the picture but testing phase can be started after the coding of the application was completed. Once a coding phase will be completed, testing team start working on the application as per the Software testing life cycle. In testing life cycle requirements have been gathered and it is divided within the team. As per the assignment, testing team will start work on the application or Project.

ISTQB - Software Development Life Cycle (SDLC)

In last article we have seen the deep explanation for CMMI Levels. Now let’s move to the other important topic of management system. It can be called ‘Software Development Life Cycle’.

Here we will understand each phase of software development life cycle. From beginning to the End how a Software or Product will be developed and launched.

We can say that every organization have different methods to develop a software and it may be designed with many different methodologies and ideas. This kind of methodology can be known as ‘Software development Modules’. Like Waterfall Module, incremental Module, RAD Module, Agile Module, Spiral Module, Prototype Module, V Module, iterative Module etc.

Every module have their own functionalities which needs to be fulfilled to develop a successful software. Software life cycle phases are designed just the way we are executing one by one steps. After ending of the one phase, all discussed requirements for that should be worked properly.
