ISQS exam 3 Ben Mitchell TTU Study Guide software development - Answer-- The multistep process of designing, writing, and testing computer programs. - SDLC works by lowering the cost of software development while simultaneously improving quality and shortening production time. SDLC - Answer-Software Development Life Cycle- The Software Development Life Cycle (SDLC) refers to a methodology with clearly defined processes for creating high-quality software. SDLC stages - Answer-Identify the problem - This stage of the SDLC means getting input from all stakeholders, including customers, salespeople, industry experts, and programmers. strengths and weaknesses Planning: - "what do we want?" determines cost and resources. design - "how will we get what we want? make a design plan called design specification and all the stakeholders will give feedback and suggestions. Failure at this stage will almost certainly result in cost overruns at best and the total collapse of the project at worst. EMILLYCHARLOTTE 2024/2025 ACADEMIC YAER ©2024 EMILLYCHARLOTTE.

It's important that every developer sticks to the agreed blueprint. code test: - "Did we get what we want?" we want to verify if the code meets the defined requirements. software deployment - "Let's start using what we got." This allows any stakeholders to safely play with the product before releasing it to the market. Besides, this allows any final mistakes to be caught before releasing the product. SDLC Methodologies - Answer-Waterfall Methodology/ Process - Every stage of a product's life cycle takes place in sequence. The progress cascades steadily downwards through these phases like a waterfall. Agile Methodology/ Process - Promotes iterative development via short, regular intervals. Development is incremental.
