# Storyline Builder A structured approach to building presentation storylines where each line becomes one slide title, creating a logical narrative flow. ## What is a Storyline? A storyline is the backbone of a presentation - a sequence of messages that tells a complete story. Each line in the storyline becomes one slide title in the final deck. **Key characteristics:** - Each line = one slide title (action-oriented message) - Logical flow from problem → context → analysis → solution - Slide titles are the message, not topics - Reader should understand the story from titles alone ## Core Principles **Action Titles** - Titles state the finding, not the topic - Good: "Market grew 40% while revenue declined 5%" - Bad: "Market Analysis" **Logical Progression** - Paint the problem or opportunity - Provide context (market, competitive landscape) - Show data to prove/disprove hypotheses - Present solution and next steps **Story Flow** - Problem → Context → Analysis → Solution → Roadmap - Each slide builds on the previous - Clear beginning, middle, end ## Storyline Templates by Situation ### 1. Market Strategy / Pitch Deck **Flow: Market opportunity → Competitive position → Product strategy → Go-forward plan** ``` Storyline: 1. [Market name] represents $XXB opportunity growing at XX% CAGR 2. We operate in [specific segment] worth $XXB with XX% growth 3. Top 3 competitors generate $XXM-XXB revenue growing XX-XX% annually 4. Our revenue of $XXM positions us as [rank/position] with XX% growth 5. [Product name] addresses [use case] for [target customer segment] 6. Top 10 customers span [industries/sectors], XX% enterprise vs XX% SMB split 7. Pricing structured as [model type] with $XX average contract value 8. Product differentiation built on [technology/approach] vs competitors 9. Key competitive advantages: [advantage 1], [advantage 2], [advantage 3] 10. Three growth opportunities identified: [opp 1], [opp 2], [opp 3] 11. Focus on [priority opportunity] based on market size and competitive position 12. 18-month roadmap prioritizes [capability 1], [capability 2], [capability 3] ``` ### 2. Internal Problem-Solving (Issue Tree Format) **Flow: Problem framing → Root cause analysis → Solution options → Prioritization → Next steps** ``` Storyline: 1. [Problem statement] - current state at XX vs target of XX 2. Problem driven by three factors: [factor 1], [factor 2], [factor 3] 3. [Factor 1] contributes $XXM impact (XX% of total problem) 4. [Factor 2] contributes $XXM impact (XX% of total problem) 5. [Factor 3] contributes $XXM impact (XX% of total problem) 6. Root cause analysis reveals [key insight from data] 7. Three solution approaches identified to address root causes 8. Solution 1: [approach] - XX% impact, $XXM investment, XX weeks 9. Solution 2: [approach] - XX% impact, $XXM investment, XX weeks 10. Solution 3: [approach] - XX% impact, $XXM investment, XX weeks 11. Prioritize [solution X] based on impact/effort analysis 12. Implementation roadmap: [Phase 1 by date], [Phase 2 by date], [Phase 3 by date] 13. Success metrics: [metric 1], [metric 2], [metric 3] tracked [frequency] ``` ### 3. Project Roadmap / Implementation Plan **Flow: Approach → Phases → Activities → Timeline → Success criteria** ``` Storyline: 1. Project objective: [goal statement with measurable outcome] 2. Four-phase approach over XX weeks: Discovery → Design → Build → Launch 3. Project roadmap spans XX weeks with clear owners and milestones: - Phase 1 (Weeks 1-X): User research - XX interviews across [segments] | Owner: [role] - Phase 2 (Weeks X-X): Solution design - Define stories, sprint planning | Owner: [role] - Phase 3 (Weeks X-X): MVP build - [features] across XX sprints | Owner: [role] - Phase 4 (Weeks X-X): Launch - Onboard XX customers | Owner: [role] 4. Core team of XX across [# domains]: PM, Design, Engineering, [other] - Gap: Need [X more roles] and $XXK investment 5. Success criteria: [metric 1] = XX, [metric 2] = XX by [date] 6. ROI measurement: Track [business metric] over XX months ``` ## How to Build a Storyline **Step 1: Identify the situation type** - Market/strategy deck? - Problem-solving presentation? - Project roadmap? - Choose appropriate template **Step 2: Customize the flow** - Replace placeholders with specific content - Add or remove slides based on story needs - Maintain logical progression **Step 3: Write action titles** - Each line should be a complete message - Include data points and specifics - Test: Can someone understand your story from titles alone? **Step 4: Verify flow** - Does it progress logically? - Are there gaps in the logic? - Does it lead to clear next steps? **Step 5: Build slides** - Each storyline becomes one slide - Slide title = storyline - Slide body supports the title message ## Common Storyline Patterns **Problem-to-Solution Arc** ``` Problem statement → Problem sizing → Root causes → Solution options → Recommendation → Implementation plan ``` **Market-to-Strategy Arc** ``` Market opportunity → Competitive landscape → Our position → Product strategy → Roadmap → Expected outcomes ``` **Analysis-to-Action Arc** ``` Key question → Hypotheses → Data analysis → Insights → Recommendations → Next steps ``` ## Usage Guidelines **When creating storyline:** - Start with the end in mind (what decision/action needed?) - Use MECE principles to organize sections - Include quantitative support where possible - Make the "so what" clear at each step **When reviewing storyline:** - Can you understand the full story from titles alone? - Is the logical flow clear? - Are titles action-oriented (not topics)? - Does it lead to clear conclusion/next steps? - Are data points specific (not vague)? ## Common Mistakes to Avoid - **Topic titles**: "Market Analysis" instead of "Market growing 40% CAGR" - **Missing the "so what"**: Data without interpretation - **Illogical jumps**: Skipping steps in reasoning - **Too granular**: 50 slides when 15 would tell the story - **No ending**: Storyline trails off without clear next steps - **Vague language**: "Good performance" instead of "Revenue grew 25%" ## Tips for Effective Storylines **Start with structure** - Outline major sections first - Fill in detailed slides within each section - Typical deck: 15-25 slides for exec presentation **Consider executive summary upfront** - Optional first slide summarizing key message - Useful for: Problem statement, recommendation, expected impact - Allows execs to get punchline immediately - Rest of deck provides supporting detail **Use parallel structure** - Keep similar sections in similar format - Makes story easier to follow - Example: If slide 5 is "Factor 1: $XXM impact", slide 6 should be "Factor 2: $XXM impact" **Include signposts** - Use section breaks or agenda slides - Help audience know where they are in story - Example: "Three drivers of the problem" followed by three slides **Build to the punchline** - Lead audience through your thinking - Don't jump to recommendations without proof - But don't bury the lede - executive summary upfront often works **Iterate** - First draft won't be perfect - Review logical flow - Get feedback before building full slides - Much easier to reorganize storyline than finished slides
