Stage-Gate Process

This guide presents a Stage-Gate Product Development Process (PDP) tailored for B2B technology companies developing hardware or integrated systems. It follows a classic stage-gate model – from initial idea through launch and post-launch review – and is designed to be modular for different project types (new products vs. incremental updates). Each stage defines clear deliverables, gate criteria (checkpoints), key stakeholders, and recommended tools. Use this as both a deployment framework and an audit checklist to improve and refine your product development process over time.

​

Why Stage-Gate? Because great products deserve more than gut instinct.

The Stage-Gate approach breaks product development into structured stages, each separated by a gate—where cross-functional leaders step in, pressure-test the work, and decide whether to go, pause, or stop. It’s not bureaucracy—it’s discipline.

With clear deliverables, tough go/kill decisions, and shared accountability across product management, R&D, marketing, operations, and finance, Stage-Gate brings visibility, alignment, and real momentum to innovation efforts.

Used right, it doesn’t slow you down—it keeps you from speeding off a cliff. Proven to boost success rates and profitability, Stage-Gate is a modern tool for smart teams building smart products. This template brings those fundamentals to life.

S0

Ideation & Concept Generation

​Generate and screen initial product ideas

  • Idea Brief or Concept Proposal

  • Preliminary Market Analysis

  • Initial Feasibility Check

  • Initial Business Case (optional)

S1

Planning & Definition

​Define product concept and business case

  • Market Requirements Document (MRD) or Product Brief

  • Full Business Case (market sizing, revenue/cost projections)

  • High-level Project Plan (scope, timeline, resources)

  • Technology feasibility studies or proof-of-concept prototype

S2

Development (Design &
Implementation)

Design and build the product

  • Detailed product specifications (engineering designs, drawings)

  • Alpha or prototype units built

  • Test plans (verification & validation plans)

  • Manufacturing plan (procurement, BOM, tooling needs)

  • Marketing plan draft (branding, initial go-to-market strategy)

S3

Validation & Testing

Test and validate the product

  • Beta units or pilot production run

  • Test reports (system verification, reliability, compliance certifications)

  • Customer/field trial feedback (validation of market acceptance)

  • Operations readiness (finalized manufacturing process, quality control, support & service plan)

  • Marketing/sales materials ready (brochures, demos)

S4

Launch and Deployment

Commercialize and scale the product

  • Product launch executed (product released to market)

  • Launch metrics tracked (e.g. early sales, customer feedback, quality issues)

  • Initial production volume and distribution in place

  • Documentation completed (user manuals, technical docs)

  • Post-launch support functioning (tech support, spare parts)

G1

Idea Screen

​Is the idea worth pursuing?

  • Clear customer problem addressed

  • Strategic alignment with markets and product strategy

  • Technical feasibility with existing capabilities

  • Business potential worth pursuing

G2

Concept Approval

Is product concept defined and feasible?

  • Product requirements address customer needs

  • Business case shows profitable opportunity

  • Technical solution proven at concept level

  • Project plan is realistic (schedule, budget)

G3

Design Freeze / Go-to-Test

Ready to proceed to validation?

  • Design meets requirements (reviewed & frozen)

  • Prototype results indicate product works as intended

  • No critical technical risks remain

  • Manufacturing and supply chain set-up is on track

  • Project timeline and costs are still acceptable

G4

Go-to-Market Readiness

Product & organization ready to launch?

  • Product passes all tests and meets specs

  • Pilot customers validate it solves their problem

  • Regulatory requirements are met

  • Manufacturing can scale to volume with quality

  • Marketing, sales, and support teams are prepared for launch

G5

Post-Launch Review

Goals met? Proceed to full commercialization or next iteration

  • Early performance indicates product meets key success metrics

  • No critical issues unmet

  • Team has plan for ongoing production and support
