Testing_104 : Software Development Life Cycle

Software Development Life Cycle (SDLC) is a process of developing various information systems.
Phases in SDLC :

1. Requirement Gathering
2. Analysis
3. Design
4. Coding
5. Testing
6. Implementation
7. Support/Maintenance

SDLC Process :
Request for Proposal [RFP] :

• ABC Insurance will prepare & distribute the RFP to selected vendors.
• Software companies will respond RFP with their proposals (Technical Solutions, Cost, Delivery schedule, Time Line and Deliverables).
• If ABC Insurance likes proposal from any vendor, then they will sign statement of work with that vendor.

Kick-Off Meeting :

• It's a high level meeting between the CTO's and Sr. Managers.
• Identify the project Manager.
• Prepare project Management plan (PMP).
• After high level meeting with customer they will release Business Requirement Specification (BRS), (Its high level document containing project requirement from customer understandable).
• Person should be a domain expert of functional Expert. He/She will be eligible to convert the BRS to SRS(Software Requirement Specification).

QA & Testing :

• Identify Standards, guidelines, procedures, checklist and templates required to develop the project.
• Review SRS (check for consistency, Completeness, correctness and testability).
• Once SRS is approved, Create a baseline for SRS (SRS 1.0v).

Development :

• Based on approved SRS software architect or Tech Lead will design the model of the project.
• Model contains
• Architectural Design (Module, Subsystems etc.)
• Database Design
• User Interface Design (Mockups & Wireframes)
• All UML Diagram
• Use case
• Class
• Object
• Sequence
• Collaboration
• Activity
• Deployment etc.

• Review and approval of the design document.

QA & Testing :

• Test Manager or Test lead (Task assigned by Test Manager) shall study the approved SRS and prepare the test plan for project based on the approved PMP.
• Review and approval of the Test Plan.
• Test Engineers are going to identify the required Test Scenarios for project (what to be tested).
• Review and approval of the Test Scenario.
• Test Engineers are going to prepare the test cases for all approved Test Scenarios.[How what to be tested]
• Review and approval of the test cases.

Development :

• Based on approved design document developers are going to convert the logic specified in the design document into programs as per chosen programming language the they will release date.
• Perform code reviews.
• Once code is reviewed and approved perform Unit Level Testing.
• Once unit level Testing is approved developers will integrate the units and release the build for testing department.

QA & Testing :

• Perform Integration level Testing.
• Perform the Retesting and Regression testing.
• Once the Integration level testing is approved, perform the system level testing.
• Perform the Retesting and Regression testing.

Development :

• Developers are going to fixing the defects which are reported by testing department.

QA & Testing :

• Once System level Testing is approved, release the application for user acceptance testing (UAT).
• Perform UAT.
• Once UAT is approved, release the application for production.
• Once product is ready, perform installation Testing.
•  Once installation Testing is approved, implement the developed software into client environment & provide user training.
• Provide support to the customer for any defects, issues & for any future enhancements.
