SigmaPro - DfSS

DFSS is a methodology for a new product, process or service design where radical breakthrough in performance is required. Most of the existing problems in a business are due to the design of the product or process involved, so the limiting factor in performance improvement becomes the overall design.

The fundamental concept of DfSS is that before commencing product or process design we must know what is expected of that process or product in detail. If a process does not achieve its goals, then either the goals where not clear from the start, or the design ahs not considered the goals properly.

DfSS uses the DMADV methodology to ensure that requirements are understood from the start, risks are properly considered, and that the process/product is designed with all the requirements built in. DfSS has many tools and methods to ensure this happens.

Define the project, problem/opportunity statement, goals and targets, scope and boundaries, key deliverables, measures and milestones Define the customers and their requirements, refine and rank requirements. Prioritise concepts. Define high level architecture define input variables and validate measurement system

Rank the relative importance of the node, define potential failure modes and prioritise risk. Select key inputs and estimate baseline design performance.

Find setting for the inputs that optimise the design output. Ensure that design meets all customer requirements. Develop test plan and confirm the performance. Finalise design tolerances and specifications. Develop control plan for final design. Close the project

Best practice means finding and using the most effective and efficient ways of working to achieve your business objectives. It involves keeping up to date with the methods that other successful businesses use, and assessing the application such methods could have within your own organisation.

Sigmapro is committed to offering best in class training services and business advice, and to support this objective we carry our research into Lean Six Sigma and publish papers to encourage debate and support best practice amongst the business community.
