Multi-Surface Product Strategy Skill
Version: 1.1 Created: 2026-02-07 Updated: 2026-02-07 Author: Manus AI Purpose: To guide the design of a coherent multi-surface product strategy where each surface (e.g., desktop, mobile, web) has a unique, complementary role.
I. The Philosophy: Complement, Don't Compete
In a multi-surface world, the biggest mistake is to build the same product on every device. A desktop app, a mobile app, and a web app should not be clones of each other. They should be complementary surfaces, each optimized for the unique context in which it will be used.
This skill is about designing a product strategy where the whole is greater than the sum of its parts. We will define the unique "job-to-be-done" for each surface and then design a seamless experience for users as they move between them.
The core principle: Surfaces are for contexts, not devices.
II. When to Use This Skill
When planning a new product that will exist on multiple surfaces
When adding a new surface (e.g., a mobile app) to an existing product
When a multi-surface product feels fragmented or confusing
During a strategic review of a product line
After using /product-positioning to identify unique value propositions
III. The Workflow
This is a 5-step workflow for designing a multi-surface product strategy.
Step 1: Identify the Surfaces
Goal: List all current and potential product surfaces.
Actions:
List the existing surfaces (e.g., web app)
Brainstorm potential new surfaces (e.g., desktop app, mobile app, browser extension)
Output: A complete list of all surfaces to consider
Step 2: Define the Core Job-to-be-Done for Each Surface
Goal: For each surface, define the primary job that users will hire it to do, based on its unique context.
Actions:
For Desktop, define the job as "deep work, complex orchestration, sustained focus"
For Mobile, define the job as "on-the-go quick capture, lightweight orchestration, glanceable status"
For Web, define the job as "discovery, onboarding, cross-platform access without installation"
For each surface, ask: "What is this uniquely good at that the others aren't?"
Output: A clear job-to-be-done statement for each surface
Step 3: Map Features to Surfaces
Goal: Map existing and potential features to the surface where they best fit, based on the core job-to-be-done.
Actions:
Create a table with surfaces as columns and features as rows
For each feature, decide which surface is its primary home
Identify features that should exist on multiple surfaces (with different implementations)
Identify features that should be surface-exclusive
Output: A feature-to-surface mapping table

Step 4: Design the Handoffs
Goal: Design the mechanisms for seamless handoffs between surfaces.
Actions:
Define the sync architecture (e.g., cloud-based, real-time, eventual consistency)
Design the user experience for handoffs (e.g., "Continue on Desktop" button on mobile)
Identify handoff triggers (e.g., "This task is too complex for mobile, switch to desktop")
Design the visual/notification system for cross-surface awareness
Output: A handoff design document with sync architecture and UX patterns
Step 5: Define the Business Model
Goal: Define the business model for the multi-surface strategy.
Actions:
Decide which surfaces are free, paid, or part of a subscription
Define the pricing tiers and what's included in each
Consider surface-specific pricing (e.g., desktop is core, mobile is premium add-on)
Plan the rollout timeline (e.g., desktop first, mobile 4-6 weeks later)
Output: A business model document with pricing and rollout plan
IV. Best Practices
1. Surfaces are for Contexts, Not Devices
Why: Users don't think "I need the mobile version." They think "I need to capture this idea quickly while I'm walking."
How: Frame each surface by its context of use, not by its device type.
2. The Handoff is the Feature
Why: The most magical part of a multi-surface strategy is the seamless handoff between surfaces. This is what makes the whole greater than the sum of its parts.
How: Invest heavily in sync architecture and handoff UX. Make it feel like one product, not three separate apps.
3. Simplicity Sells
Why: Each surface should be ruthlessly simple, focused on its core job-to-be-done. Feature bloat kills the magic.
How: Resist the temptation to add every feature to every surface. Say no to features that don't align with the surface's core job.
4. Start with One Surface, Expand Strategically
Why: Building multiple surfaces simultaneously is expensive and risky. Start with the core surface, prove the value, then expand.
How: Launch desktop first (for deep work), then add mobile (for on-the-go) once desktop is stable.
5. Design for Asymmetry
Why: Symmetrical multi-surface strategies (same features everywhere) are boring and wasteful.
How: Embrace asymmetry. Make each surface uniquely valuable. Users should want both, not just one.
V. Quality Checklist
Before delivering the strategy, ensure you can answer "yes" to all of the following questions:
Have you identified all potential product surfaces?
Have you defined a clear and unique job-to-be-done for each surface?
Have you mapped all key features to their primary surface?
Have you designed a seamless handoff experience between surfaces?
Have you defined a clear and sustainable business model for the multi-surface strategy?
Have you planned a realistic rollout timeline?
Have you identified which features should be surface-exclusive?
VI. Example: Dojo Genesis Desktop + Mobile Strategy
The Problem: We had a web app but needed to decide whether to build desktop, mobile, or both.
The Process:
Identified Surfaces: Desktop (Electron), Mobile (PWA/Native), Web (existing)
Defined Jobs:
Desktop: Deep work, complex multi-agent orchestration, sustained focus sessions
Mobile: On-the-go task capture, quick status checks, lightweight orchestration
Web: Discovery, onboarding, lightweight access without installation
Mapped Features:
Complex orchestration → Desktop primary
Quick capture → Mobile primary
Onboarding → Web primary
Designed Handoffs:
Cloud sync via backend API
"Continue on Desktop" button in mobile app
Real-time status updates across surfaces
Defined Business Model:
Desktop: Core product ($20/month)
Mobile: Premium tier (separate subscription, launched 4-6 weeks after desktop)
Web: Free tier for discovery
The Outcome: A clear, asymmetric multi-surface strategy where each surface has a unique value proposition. Desktop for deep work, mobile for on-the-go.
Key Decision: We chose Route 4 (Hybrid - PWA now, native later) to de-risk mobile development while shipping desktop first.
VII. Common Pitfalls to Avoid
Pitfall 1: Building the Same Product on Every Surface
Problem: Users don't see the value in having multiple surfaces if they're all the same.
Solution: Define unique jobs-to-be-done for each surface and map features accordingly.
Pitfall 2: Ignoring the Handoff Experience
Problem: Users get frustrated when they can't seamlessly move between surfaces.
Solution: Invest in sync architecture and handoff UX from day one.
Pitfall 3: Feature Bloat on Every Surface
Problem: Trying to add every feature to every surface leads to complexity and confusion.
Solution: Be ruthlessly simple. Each surface should focus on its core job-to-be-done.
Pitfall 4: Building All Surfaces Simultaneously
Problem: Building multiple surfaces at once is expensive, risky, and dilutes focus.
Solution: Start with one core surface, prove the value, then expand strategically.
Pitfall 5: Symmetrical Pricing
Problem: Charging the same for all surfaces doesn't reflect their different value propositions.
Solution: Consider surface-specific pricing (e.g., desktop as core, mobile as premium add-on).

Examples
Scenario 1: "We have a web app and are about to build a desktop app. Should mobile be next?" → Surface audit identifying web's unique job (discovery/onboarding), desktop's job (deep focused work), and a recommendation to defer mobile until desktop v1 ships, with a PWA path to validate mobile demand first.
Scenario 2: "Our users complain the desktop and mobile apps feel like completely different products." → Feature-to-surface audit revealing feature overlap (same screens duplicated across both), followed by a re-mapping that strips mobile down to quick-capture and status-check flows and removes them as primary on desktop.
Edge Cases
If the product has only one surface today, skip Step 4 (handoff design) and focus Steps 1-3 on what the second surface should uniquely own before committing to build it.
If the user already has a clear surface strategy but wants to add a fourth surface (e.g., CLI or voice), run only Steps 2-4 scoped to the new surface — do not re-litigate existing surfaces.
If a surface is being retired (not added), redirect to product-positioning first to confirm the retirement decision is not a false binary before proceeding.
Anti-Patterns
Producing a strategy where every surface has the same primary features — this defeats the purpose of the skill; each surface must have at least one feature the others do not.
Designing handoffs without specifying the sync mechanism (real-time vs. eventual consistency vs. manual export) — handoff UX is impossible to evaluate without a concrete sync model.
Recommending all surfaces be built simultaneously — this skill should always produce a phased rollout with a single lead surface.
Framing surfaces by device type ("the phone app") instead of context of use ("the on-the-go capture surface") — device framing leads to feature parity thinking rather than job-to-be-done differentiation.
