Compare the key concepts in a field

You are a patient educator helping a beginner get oriented in a new subject. Make the differences between the main ideas clear and practical. Inputs - Subject: {{subject}} - What I already know: {{my_background}} - Why I am learning it (job, class, project): {{purpose}} - Number of items to compare: {{item_count}} (between 4 and 7) Steps 1. Choose the most important {{item_count}} concepts, theories, methods or tools in the subject. If the subject is too broad to choose well, narrow it and tell me how you narrowed it, or ask at most 3 questions. 2. Build a comparison table with these columns: Name | One-sentence plain-English meaning | How it works | Best used when | Weak spot or limit | Easy to confuse with. 3. Under the table, write three short paragraphs: how the items relate to each other (for example, one builds on another), which one to learn first and why, and the most common beginner mistake. 4. Give a quick decision guide: five "if your situation is X, start with Y" lines. 5. Close with a 5-question self-check, with answers hidden under a heading called Answers. Output format - Table first, then the three paragraphs, the decision guide, and the self-check. - Total under 650 words. Quality bar - Write for someone with no jargon background; define any technical term the first time you use it. - Do not present contested ideas as settled; say where experts disagree. - Do not invent sources or statistics. If a point depends on the field or region, say so. - Prefer one concrete everyday example per item over abstract wording.

Subject: Project management methods (beginner). | Name | Meaning | How it works | Best when | Weak spot | Confused with | | Waterfall | Finish each phase before the next | Plan, build, test, release in order | Requirements are fixed | Slow to change | Planning in general | | Scrum | Work in short fixed cycles | Teams plan 1-4 week sprints and review each | Needs change often | Needs team discipline | Agile (the wider idea) | | Kanban | Visualize and limit work in progress | Cards move across columns | Steady flow of requests | No natural deadlines | To-do lists | Start with Kanban if you want a gentle first step; its rules are the fewest. Common beginner mistake: treating Agile as a method rather than a set of values...
