SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and assets (resource) components.

What problem does it solve? Starting a Six Sigma improvement project without a clear problem definition, measurable customer requirements, or sponsor authorization leads to scope creep and failed projects. This Skill structures the DMAIC Define phase so teams produce a complete, approvable Project Charter before investing in measurement and analysis. ## Core Features & Use Cases - VOC to CTQ Conversion: Collects Voice of Customer data using six documented techniques (interviews, surveys, complaint analysis, Gemba, focus groups, support data) and converts it into measurable Critical-to-Quality requirements. - Project Charter Generation: Produces a formal charter with Problem Statement, Goal Statement, Business Case, SIPOC process map, scope boundaries, RACI matrix, and DMAIC timeline using a ready-made template. - Quality Gates and Red Flags: Enforces sponsor tollgate approval and flags common Define-phase failures such as CTQs without VOC data or problem statements that assume causes. - Use Case: A logistics team seeing 18% late deliveries uses this Skill to interview customers, define CTQs like on-time delivery percentage, map the fulfillment SIPOC, and get a signed charter before starting the Measure phase. ## Quick Start Start the DMAIC Define phase for my delivery-delay improvement project and help me build the Project Charter with VOC, CTQs, and SIPOC.

Frequently Asked Questions about dmaic-define

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write a Six Sigma problem statement?▼

A good problem statement describes an observable symptom with a quantified magnitude, a time period, and a business impact, without mentioning causes or solutions. For example: 18% of orders miss the promised date (Jan-Mar 2026), costing $45K monthly in credits.

How do I convert VOC into CTQs?▼

Convert Voice of Customer statements by identifying the underlying need, then defining a measurable metric with a specification. For example, 'orders arrive late' becomes the need for on-time delivery, measured as percentage of orders delivered by the promised date with a 95% target.

What is a SIPOC diagram and how do I build one?▼

A SIPOC maps Suppliers, Inputs, Process, Outputs, and Customers at a high level to define project scope. Build it in order: define 5-7 process steps first, then outputs, customers, inputs, and finally suppliers.

When should I not use DMAIC for process improvement?▼

Skip DMAIC for simple problems solvable in a PDCA cycle, when the root cause is already confirmed (go straight to Improve), or when no sponsor exists. DMAIC requires formal authorization and resources to succeed.

What are common mistakes in the DMAIC Define phase?▼

Common failures include CTQs defined without real customer data, problem statements that assume a solution, SIPOCs with too many steps indicating oversized scope, business cases without financial numbers, and charters lacking genuine sponsor approval.
