CSS CS Optional — Paper-I, Section-B, Topic V.

🔑 Definition

• Software Process = structured set of activities to turn a requirement into a delivered, working system.

📌 Generic Process Activities (all models = different arrangements of these 4)

• Specification — what should the system do, under what constraints.
• Development — design + implementation.
• Validation — checking it does what was asked.
• Evolution — changing it as needs change after delivery.

📌 Umbrella Activities (run throughout, not at one stage)

• SQA
• Project tracking
• Risk management
• Documentation
• Measurement/metrics

⚠️ MCQ Trap

• Happens once, at one stage → process activity.
• Happens continuously across the project → umbrella activity.
• e.g. Risk management = umbrella, NOT one of the 4 generic activities.
