The 9 phases of the Software developmental life cycle are 1). Feasibility Study Phase 2). Requirement Phase 3). Design phase 4). Construction phase 5). Testing Phase 6). Release phase 7). Software maintenance 8). Software Configuration Management 9). Project Management Processes.

I know what each phase does but I'm having problems with figuring out concerns. And the second part of the question asks about the waterfall method for each phase and I's having trouble with that too.

For each of the nine phases in the Software Development Life Cycle, answer the following 2 questions. 1. What is the primary concern (or concerns) ofthis phase? 2. If this is a Waterfall project, what are the expected outcome artifacts (document, product, or result expected to come out of this phase
