Designarrow_forwardYour company is upgrading the existing system to cater for new functionalities as required by thecompany. You are to manage this project and you have identified six key project stages:i) Specification of upgrade requirements;ii) Software Configuration;iii) Software Customisation;iv) Functionality testing;v) Migration;vi) DeploymentDraw up a work breakdown structure (WBS) for the project based on the following requirements:• At least three levels.• At least three different activities under each deliverable.arrow_forwardThe System Development Life Cycle (SDLC) is a structured approach used in IT to ensure the consistent development of high-quality systems. It facilitates efficient resource management, risk mitigation, and clear stakeholder communication throughout the development process. By emphasizing thorough documentation, user-centered design, and continuous feedback, the SDLC ensures the system's relevance and effectiveness over time. Discuss the impact AI might have on this process and how it might streamline this process.arrow_forward
