Output

What the skill generates for you

Your PM → Senior PM Advancement Plan

Executive Summary

You’re well-positioned for Senior PM at 18 months tenure, but need to develop Product Strategy and Organizational Influence to advance. The core difference: PMs execute features with direction from leadership, while Senior PMs own product strategy and drive cross-functional alignment independently.

Timeline: 6-9 months of focused development
Key gaps: Product strategy ownership, cross-functional leadership, scaling impact
Leverage strengths: 18-month tenure shows commitment, startup context provides visibility

Level Comparison: PM vs Senior PM

Dimension	PM (Current)	Senior PM (Target)
Scope	1-2 features within single product area	Full product or major vertical
Strategy	Executes roadmap defined by leadership	Creates product vision, owns quarterly roadmap
Autonomy	Receives direction on what to build	Self-directed within product area
Stakeholders	Eng team + 1-2 other functions	Leads across eng, design, marketing, sales, success
Time Horizon	Sprint-to-sprint	Quarter-to-quarter
Impact	Feature adoption, user satisfaction	Product-level metrics: revenue, retention, strategic outcomes

Competency Gap Analysis

Product Strategy ⚠️ (Major Gap)

Current: Likely executing roadmap items defined by senior leadership
Target: Creates vision docs, defines roadmaps, makes strategic tradeoffs
Specific behaviors missing:

Writing product vision documents (12-month direction)
Leading quarterly planning with cross-functional input
Presenting product strategy to VP/exec leadership
Making strategic tradeoff decisions (feature A vs B, build vs buy)
Conducting competitive analysis and market research independently

Influence & Leadership ⚠️ (Moderate Gap)

Current: Collaborating within immediate team
Target: Leads cross-functional initiatives without direct authority
Specific behaviors missing:

Leading initiatives requiring buy-in from 3+ teams
Creating alignment among stakeholders with competing priorities
Influencing product decisions at leadership level
Mentoring junior PMs or driving PM process improvements

Business Acumen ⚠️ (Moderate Gap)

Current: Tracking feature-level metrics
Target: Owns product-level business metrics, understands unit economics
Specific behaviors missing:

Owning product-level KPIs (not just feature metrics)
Articulating ROI of product investments
Understanding unit economics and business model implications
Connecting product decisions to company-level OKRs

Customer Insight ✓ (Minor Gap)

Current: Conducting research for assigned features
Target: Building systematic voice-of-customer programs
Development needed: Scale from tactical research to strategic customer insight programs

Product Execution ✓ (Likely Strong)

Current: At a startup for 18 months, execution is likely solid
Gap: Maintain strength while developing other areas

Key Insight

The fundamental shift from PM to Senior PM is from executor to strategist:

PMs answer: “How do we build this well?”
Senior PMs answer: “What should we build and why?”

At a 100-person startup, visibility is your advantage—use it. Senior PMs don’t just execute better; they create clarity for others. Focus 70% of development energy on Strategy and Influence, the two areas that most distinguish Senior PMs.
