SDLC Stage Dimensions – Shape

Purpose

The Shape Stage defines how the vision becomes feasible — transforming ideas and validated insights from Discovery into a delivery-ready plan.
It establishes scope, architecture vision, delivery approach, and feasibility, aligning all parties on what will be built, how, and under which constraints.

Shape is where strategy meets execution.
It converts the “why” and “what” discovered earlier into “how” — preparing teams, stakeholders, and systems for sustainable delivery flow.
When done well, Shape minimizes delivery risk, sets realistic expectations, and becomes the contract of shared understanding between Client and Vendor.

Core Outcomes

Outcome	Description
Delivery Vision	A coherent, outcome-aligned vision that translates business goals into tangible delivery objectives.
Scope Definition	A prioritized backlog or roadmap describing what will be built, when, and why.
Architecture Vision	A documented target architecture and rationale aligned with scalability, security, and maintainability.
Feasibility & Estimation	Validated assumptions, complexity estimates, and resource forecasts.
Delivery Model & Governance	Clear engagement model, communication cadence, and decision-making process.

Shape Dimensions

1. Strategic Alignment

Defines how well Shape connects the validated Discovery findings to actionable scope and measurable outcomes.

Aspect	Low Maturity (Reactive)	High Maturity (Proactive)
Goal Translation	Discovery outputs not reflected in scope.	Goals translated into product outcomes and acceptance metrics.
Prioritization Logic	Everything is “must-have.”	Prioritization driven by value, risk, and effort balance.
Outcome Traceability	Delivery tasks disconnected from strategic goals.	Each backlog item traces to a defined business outcome.
Vision Communication	Technical or business bias dominates.	Shared, human-readable vision understood by all stakeholders.

Improvement Strategies

• Use VMOSA (Vision, Mission, Objectives, Strategies, Actions) or Impact Mapping.
• Apply Outcome-based Roadmapping — link objectives to measurable impacts.
• Create a single-page delivery vision reviewed jointly with all key stakeholders.

2. Planning & Flow

Defines how scope, estimation, and delivery model are structured to balance feasibility with adaptability.

Aspect	Low Maturity	High Maturity
Scope Definition	Overly detailed or incomplete.	Balanced between high-level themes and well-shaped backlog.
Estimation Method	Based on assumptions, not validated data.	Multi-method estimation (PERT, T-shirt sizing, story points) with uncertainty range.
Delivery Model Choice	Model dictated by contract or inertia.	Model adapted to context (Fixed-Bid, Time & Material, Co-Delivery).
Roadmap Structure	Dates arbitrary, dependencies unclear.	Milestones based on value increments and dependency analysis.

Improvement Strategies

• Introduce progressive estimation — refine scope iteratively.
• Use Scenario Planning for budget and timeline alignment.
• Align delivery model choice with Contextual Drivers (commercial, organizational, technical).

3. Collaboration & Communication

Defines how decisions are co-created and communicated between client and vendor roles.

Aspect	Low Maturity	High Maturity
Decision-Making	Centralized, delayed, or ambiguous.	Distributed decisions within defined RACI and escalation paths.
Stakeholder Involvement	Limited to approvals.	Stakeholders actively contribute to trade-offs and prioritization.
Communication Flow	Channel chaos, undocumented agreements.	Clear communication map, meeting cadences, and shared documentation.
Cross-Discipline Integration	Product, design, and engineering operate separately.	Joint shaping sessions, shared artifacts, and synchronized priorities.

Improvement Strategies

• Define Governance Cadence — e.g., weekly sync, bi-weekly steering.
• Maintain a Shape Log capturing decisions, rationales, and risks.
• Use Collaboration Maps to visualize stakeholder engagement and information flow.

4. Quality & Risk Management

Defines how feasibility, architecture, and delivery risks are identified and controlled before Build starts.

Aspect	Low Maturity	High Maturity
Architecture Vision	Implicit or over-engineered; lacks trade-offs.	Architecture designed collaboratively with rationale and constraints.
Feasibility Testing	Feasibility assumed, not validated.	Risk spikes and POCs used to confirm critical assumptions.
Technical Debt Awareness	None — “we’ll fix it later.”	Debt potential logged with mitigation options.
Definition of Ready	Missing or vague.	Agreed entry criteria for Build with clear acceptance boundaries.

Improvement Strategies

• Apply Architecture Decision Records (ADR) and Architecture Runway.
• Create Feasibility Register — track technical risk, cost, and decisions.
• Align readiness checklist with Build expectations (DoR, environments, design assets).

5. Learning & Adaptation

Defines how discovery insights, decisions, and risks evolve into an adaptive delivery mindset.

Aspect	Low Maturity	High Maturity
Feedback Integration	Discovery learnings ignored.	Discovery insights explicitly embedded into scope and architecture.
Reflection on Trade-offs	Decisions made without review.	Retrospective held to assess shaping quality and stakeholder alignment.
Adaptability to Change	Contract or timeline blocks adjustments.	Scope change process defined and integrated into governance.
Knowledge Continuity	Handovers inconsistent or undocumented.	Shape artifacts consolidated in accessible, shared repositories.

Improvement Strategies

• Conduct a Shape Retrospective after final sign-off.
• Maintain a Decision Register — track what changed, why, and impact.
• Use Knowledge Handover Packages (vision, architecture, roadmap) for Build readiness.

Common Failure Modes

Failure Mode	Root Cause	Correction
“We’re shaping while building.”	Discovery incomplete, Shape rushed.	Separate timeboxes and exit criteria for each stage.
“The backlog is too vague to start.”	Missing DoR and architecture clarity.	Enforce readiness validation and backlog refinement.
“Estimates keep changing.”	Scope or assumptions not validated.	Document estimation assumptions and uncertainty ranges.
“Client expects more than planned.”	Value and scope poorly communicated.	Present scope through outcomes, not features; revalidate alignment.

The illusion of precision — detailed plans built on unvalidated inputs — is a recurring trap. Shape aims for confidence, not certainty.

Measuring Shape Health

Signal	Description
Shared delivery vision and roadmap approved by both Client and Vendor.	Alignment achieved.
Architecture and feasibility validated via ADRs and POCs.	Technical confidence established.
Prioritization matrix links outcomes, effort, and risk.	Informed decisions made.
Definition of Ready checklist accepted by Build team.	Clear transition into Build.

Quantitative indicators:

• % of backlog items meeting DoR criteria.
• Estimation confidence range (± deviation vs. actual).
• Stakeholder alignment score (via feedback survey).

Shape and Relationship Maturity

The Shape stage moves the relationship from Aligned Autonomy toward Shared Ownership.
Here, trust grows through joint decision-making and transparent trade-offs.

High-maturity shaping:

• Builds shared accountability for both outcomes and constraints.
• Replaces handovers with collaboration.
• Aligns product ambition with delivery feasibility.

Summary

• The Shape Stage translates understanding into a feasible, outcome-driven delivery plan.
• Its five dimensions — Strategic Alignment, Planning & Flow, Collaboration, Quality & Risk, Learning & Adaptation — ensure scope, architecture, and delivery model coherence.
• Mature shaping ensures Build starts with confidence, autonomy, and transparency.
• When Shape fails, all later stages pay the cost — when it succeeds, the system flows.
