  Software development life cycle The SDLC Life Cycle, or just the SDLC as it’s known, is the process of developing software to meet a need or solve a problem. This life cycle involves quite a few steps. Planning The first stage of any project is the planning stage. In the Software Development Life Cycle (SDLC), this is where the appropriate people discuss the goals of the project, and how to run the project. A project needs to be planned before it starts. This ensures it is well run and achieves the goals that it is supposed to. It doesn’t matter if it’s a slight change to a website, or a large system being implemented, there is some level of planning done at the start of the project. Roles involved : Project Manager, Project Sponsor, other business representatives Analysis      Majority of the investigation is done in this phase, where the analysis is done to find out what the business problem is, what the detailed targets are, what the so...

Business requirement document: This document contains the client requirements in high level.These requirements can be one-liner, a statement or user stories, It depends on the client. Business analyst use some requirement Gathering Techniques like Questionnaires, One-One Interviews, Group Discussions etc to design this document. This document generally does not have solution for the requirement in it.  This document answers what the business or the client requires from our side to be done. Functional requirement document: In general this document is prepared once the Business requirement document is being mutually accepted by both the sides(Client and the business analyst). Functional requirement document is designed with solution and the workflow to achieve the business requirements in terms of the product’s intended capabilities, look and feel, and User interface. This document is mainly targ...

1.Requirement analysis: A feasible study on the business requirement and understanding the software requirements. Establish the environment requirements. Prepare the higher level test plan including the risk and tools used in the project. Establish defect tracking methodology. Identify the type of the testing to be carried in the project. 2.Design: Prepare the Data Flow Diagram (DFD) of the project and document it. Verify the flow of the functionalities. Since, QA reviews the design as an end user's perspective. Verify the user type and the user interface/experience. Prepare the low-level test plan including risk, scope, tools, environment etc. 3.Development: Develop the test case so that it can be used in TDD or BDD. Preparation of Environment for testing. 4.Testing: Execute the test case.  Finding the defect and report them as early as possible. Verify the bugs are fixed before release Perform the following testing and assure that no d...

Use case:   Defined as the path that an user might adopt in order to achieve the goal.  The use case will describe multiple paths that the user can follow within the use case. The use case are prepared in the form of actor and system. Test case: A test case represents one set of inputs that exercises a single use case scenario. For example: Lets consider account creation. An user might fill in all the fields and try creating or might not likely to produce some of the information while creating. such types of path that a user initiates are known as use case and the steps that are being performed by an user for a successful completion of use case are the test case. 

This is an approach generally adopted for any application development process which is being recognized and accepted globally. It is a set of structured program or task that any organisation would follow for an efficient and productive product, they deliver in each release. The SDLC consist of the following framework as follows, 1.Planning and requirement analysis. 2. Defining the requirement: Developing the SRS (Software requirement specification) from the gathered requirement. 3.Designing the product architecture.: With the complete SRS document a design document specification is prepared which is composed of all the architectural modules even the communication and data flow with in the. 4.Development: The development phase is totally in relationship with the DDS. 5.Testing: In modern SDLC model testing is being implemented over all the stages. 6.Maintenance: This is mainly done for the existing customers once the product is being released and b...
