What are the different phases of SDLC ?

Answer Posted / abhishek chhetri

Need Stage: An end user suspects that it would be more efficient to computerize a manual process he/she is currently working with.

2. Conceptualization Stage: The end user meets with the Systems Manager to discuss the problem and determine if it is feasible to computerize that particular application.

3. Design Stage: The end user discusses with a System Analyst what functions are needed and what the outputs should look like.

4. Technical Design Stage: The Systems Analyst designs a technical blue print or technical specification (specs) on every aspect of the system.

5. Coding/Development Stage: The design stage is where the basic logic or skeleton of the system is laid out.

6. Testing Stage: The Programmers test for errors in the syntax of the code and ensures that the logic of the programs obtains the desired results.

7. Documentation Stage: The Programmer or Technical Writer documents what the logic of their particular program is.

8. Production Stage: The application is placed into use. The Systems Analyst will then train the users on how to use the system.

9. Maintenance/Enhancement Stage: The maintenance/enhancement stage occurs when a change needs to be added to a program. This may occur because additional information or functionality is required out of the application by the end user.
