Answer / sandu
There are seven stages of the software development lifecycle
1. Initiate the project – The users identify their
Business requirements.
2. Define the project – The software development team
translates the business requirements into system
specifications and put together into System Specification
Document.
3. Design the system – The System Architecture Team
designs the system and write Functional Design Document.
During design phase general solutions re hypothesized and
data and process structures are organized.
4. Build the system – The System Specifications and
design documents are given to the development team code the
modules by following the Requirements and Design document.
5. Test the system - The test team develops the test
plan following the requirements. The software is build and
installed on the test platform after developers have
completed development and Unit Testing. The testers test
the software by following the test plan.
6. Deploy the system – After the user-acceptance
testing and certification of the software, it is installed
on the production platform. Demos and training are given to
the users.
7. Support the system - After the software is in
production, the maintenance phase of the life begins.
During this phase the development team works with the
development document staff to modify and enhance the
application and the test team works with the test
documentation staff to verify and validate the changes and
enhancement to the application software.

pseudo code.

(IV) Coding Phase:
Developer will convert the pesudo code into their language.
(V) Testing Phase:
Testers will do the testing the product r project.
