+# Management Consulting Plugin
+
+Skills for consulting-grade deliverables. These rules apply to all of them.
+
+## Writing Style
+
+Write like a senior consultant, not like an AI describing what a senior consultant would write.
+
+- No em-dashes. Use parentheses or periods instead.
+- Vary sentence length. Short sentences land points. Longer ones handle nuance.
+- State opinions directly. "This approach failed because..." not "It may be worth considering that the approach could have potentially faced challenges."
+- No "not just X, but Y" constructions. Say what it IS.
+- Quantify when possible. "Revenue dropped 12%" not "Revenue experienced a significant decline."
+- When uncertain, say so plainly: "We don't have enough data to call this yet."
+- Go deep where insight lives, light where routine. Not every section deserves equal airtime.
+- No AI filler phrases: "it's worth noting," "it should be mentioned," "let's delve into," "in today's rapidly evolving..."
+
+## Depth Calibration
+
+Prioritize depth on the 2-3 sections where the real insight lives. Don't give every section equal airtime. If the problem is clearly in one area, go deep there and sketch the rest. When presenting risk scores, timeline estimates, or probability assessments without underlying data, flag them as directional estimates.
+
+## Content Integrity
+
+- Ask for information rather than fabricating it. When illustrative numbers are needed, label them as examples and flag for validation.
+- Present benchmarks as illustrative, not authoritative. Always note the source and context.
+- Never fabricate engagement experience or specific dollar figures. Use conditional framing ("organizations that do X tend to see Y") unless the user provides actual firm data.

+# Management Consulting Plugin
+
+A management consulting plugin primarily designed for [Cowork](https://claude.com/product/cowork), Anthropic's agentic desktop application — though it also works in Claude Code. Covers the full engagement lifecycle from problem definition through implementation and closeout. Helps with hypothesis-driven analysis, business cases, client deliverables, change management, and project governance. Works with any consulting team — standalone with your input, supercharged when you connect your project tracker, knowledge base, and other tools.
+
+## Installation
+
+```bash
+claude plugins add knowledge-work-plugins/management-consulting
+```
+
+## Skills
+
+Domain knowledge Claude draws on automatically when your work touches consulting topics:
+
+| Skill | Description |
+|---|---|
+| `strategic-analysis` | Hypothesis-driven decomposition, issue trees, MECE analysis, and named framework application (Five Forces, PESTLE, 7S, VRIO, etc.) |
+| `financial-modeling` | Business case math, ROI/NPV/IRR, sensitivity analysis |
+| `client-deliverables` | Consulting reports, executive presentations, top-down structured communication, storylining, data visualization |
+| `change-management` | Transformation planning, resistance management, adoption tracking |
+| `due-diligence` | Commercial, operational, and strategic assessment |
+| `engagement-setup` | Kickoff planning, discovery phase, stakeholder mapping |
+| `implementation-planning` | Options evaluation, business cases, roadmaps, implementation plans |
+| `org-design` | Operating model and organizational structure design |
+| `engagement-pricing` | Pricing consulting engagements: fee structures, rate cards, commercial terms |
+| `process-excellence` | DMAIC, value stream mapping, process improvement |
+| `project-closeout` | Deliverable handover, lessons learned, transition planning |
+| `project-governance` | RACI, steering committees, stage gates, status reporting, risk tracking |
+| `proposal-development` | RFP analysis, proposal writing, SOW creation, pitch decks |
+| `thought-leadership` | POVs, white papers, case studies, research content |
+| `workshop-facilitation` | Workshop design, facilitation techniques, participant engagement |
+
+## Example Workflows
+
+### Scoping a new engagement
+
+Start with the problem. Describe the client situation and what they're asking for:
+
+```
+A mid-market SaaS company is losing enterprise deals to a competitor.
+They want to understand why and what to do about it.
+Help me structure the engagement.
+```
+
+The `strategic-analysis` skill kicks in to build an issue tree and hypotheses. `engagement-setup` helps plan the discovery phase and stakeholder mapping. `proposal-development` can then turn that into a scoped SOW with workstreams, timeline, and pricing.
+
+### Building a strategic recommendation
+
+You've done the analysis and need to pull it together:
+
+```
+We've completed our market analysis for the client's expansion into Southeast Asia.
+Here are our findings: [paste or upload data].
+Help me build the recommendation deck.
+```
+
+`strategic-analysis` structures the analysis (market attractiveness, competitive positioning). `financial-modeling` builds the business case with scenarios. `client-deliverables` shapes the storyline, slide structure, and detailed appendix.
+
+### Running a transformation programme
+
+The client has approved the strategy and you're into implementation:
+
+```
+We're restructuring the client's supply chain operations across 3 regions.
+12-month programme, 4 workstreams, steering committee meets monthly.
+Help me set up the governance and tracking.
+```
+
+`project-governance` builds the RACI, stage gates, and reporting cadence. `change-management` maps stakeholder impact and resistance risks. `implementation-planning` lays out the roadmap with dependencies. `workshop-facilitation` helps design the kickoff sessions with regional teams.
