List and briefly describe each activity of the SDLC core processes Build, test, and integrate system components and Complete system tests and deploy solution.

Explanation

      1) Description for SDLC core processes is given below in points:     

  • Develop the software: The programmer writes the programming code to develop the software.
  • During the making of complete software, small codes known as unit, are built and before integrating the whole software, unit testing is done.
  • The programming codes are tested by programmers to identify, whether the program is working properly or not.
  • Identify and create test cases: In this step, the test cases are written to check, whether the software is working in all conditions or not.
  • Integrate and test components: After the successful completion of all the test cases, all the modules are integrated into one unit, which acts as a smooth processing software application.

      2) Complete system tests and deploy the solution activities are given below:

  • Perform system performance and stress tests: Once the system is developed, the developer can test the system performance. Stress testing is performed to determine the performance and working of a system in heavily loaded situations.
  • Perform user acceptance tests: UAT is performed generally by the customers, which ensures that the application is working according to the requirements and no error occurs while running the application.
  • Convert existing data: The database is very important for running the application smoothly. With the changes in time and application, it is very important to update the database.
  • Create training materials and conduct training: By giving training materials and training sessions to end users, the end users understand how to run the system.
  • Configure and setup production environment: Setting up the environment, where the system can be used properly.
  • Deploy the solution: The deployment of the solution depends on both the implementation as well as testing of the product. After successful testing of the system, it can be deployed into the workable environment of the end user.

Verified Answer

The activities of the SDLC core processes are as follows:

 

      1) Developing, Testing and Integrating system, whose activities are given below:

  • Develop the software: The software is built according to customer needs.
  • Unit test is performed on the software: Unit test determines, whether the small units of the software are working smoothly without any error or not.
  • Identify and create test cases: A tester should identify all the cases for determining any error in the software and then write the test cases on identified cases.
  • Integrate and test components: All the software components are integrated and then tested.

 

      2) Complete system tests and deploying the solution whose activities are given below:

  • Perform system and stress tests: The performance of the system is monitored and its efficiency in a heavily loaded situation is also determined.
  • Perform user acceptance tests: This testing is performed by the end user in actual space, where the system/software is to be used.
  • Convert existing data: Add or change the data in the database, according to changes required by the product.
  • Create training materials and conduct training: Training material is given to the users and end users of the product and training is also given to the users.
  • Configure and setup production environment: One has to ready the supporting hardware and software, before working on a new application or product.
  • Deploy the solution: After implementing and testing the product, one can use that product or software.
