TRIZ within DFSS (DESIGN FOR SIX SIGMA)

Define TRIZ

Explore the "evolutionary development" of the prime system through cross industry benchmarking.

Identify any "new technology" resource through technical benchmarking.

Enhance the project (MGP)(Multi Generation Plan) and update the project charter with feedback from TRIZ.

Identify a conflict to resolve that will clearly benefit the project, business, and customer.

Seek new resources from technology developments and other industries. Consider potential resistance to new innovation from key stakeholders.

Measure TRIZ

Model potential conflicts using "tool-action-object" and extended process/system mapping. Use "nine screens" and MGP for view of the wider picture. Identify potential "trade-off", working from the interaction roofs of the houses of quality. Locate idle of future "resource." Evaluate the potential for improvement and innovation during conceptual and technical design. Identify all the key issues around the real and potential conflicts, including trade-offs between customer requirement or product features. Document possible and current idle resources to hand. Undertake more extensive benchmarking if appropriate. Feedback to, and support of the main DFSS project.

Analyze TRIZ

Move to one or more "inherent contradictions." State "ideal final solution." Constrain problem to an appropriate part of the new system or process. Identify the correct problems to solve together with the potential gap for improvement. Set up the final framework for the conflict resolution stage.

IMPROVE TRIZ

Generate "potential solutious," first a conceptual level then at detailed technical levels. Use "40 inventive principles" and "contradiction matrix." Evaluation and refinement iterations are required. Use all the available tools, especially but not exclusively the 40 Inventive principles, to derive inventive solutions. Evaluate against the ideal final result and repeat this loop.

Control TRIZ

Implement "solutions" through the various design stages. Institutionalize "key learnings." Update "documentation" and system model. Predict ahead for a second generation and update the MGP. Use the best solutions generated to progress the design at all levels. Repeat the conflict management loop as required, and follow with appropriate updates to documentation and the corporate memory.

Cybersecurity - Equifax sued over massive data breach

Cybersecurity Equifax sued over massive data breach Second case brought against company for way it handled personal info ATLANTA  - A team of lawyers has filed a class-action lawsuit against Equifax over that data breach that has compromised the personal information of more than 140 million US consumers. The lawsuit filed in US District Court in Atlanta faults Equifax for "gargantuan failures to secure and safeguard consumers' personally identifiable information -- and for failing to provide timely, accurate and adequate notice" to consumers that such sensitive material had been stolen. The lawsuit said plaintiffs Brian Spector of Florida and James McGonnigal of Maryland are each victims of the breach.  McGonnigal alleges he has "recently had four credit accounts opened in his name without his authorization."   The lawsuit joins another filed this past week in Oregon on behalf of a couple there, and others are expected.  A US House committee has

IP 23 Feedback

IP 23 Chaperone/Feedback Feedback by closing the loop between the output or product of a process and the controlling or influencing inputs. Introduce feedback. Enhance or change existing feedback. Monitor and control inputs rather than simply inspect outputs. Continuous coursework and assessment rather than end of the year exams. Many processes, typically continuous flow production, electronics or service processes, are part of larger systems. Such systems are best controlled using closed loop feedback, where the state of one or more critical outputs is used to influence one or more critical inputs. Making feedback work well is a challenging subject, as over control is just as problematic as under control. However the aim must be to ensure effective feedback loops are in place within processes where they will clearly help. Feedback is essential as part of system's control mechanisms. Six Sigma encourages the concept and use of the formula Y=f(x), where we control the inputs to a

TWO MINDSETS

Two different mindsets are doing battle in today's world. Old Power Values Formal (representative) governance, managerialism, institutionalism Competition, exclusivity, resource consolidation Confidentiality, discretion, separation between private and pubic spheres Expertise, professionalism, specialization Long-term affiliation and loyalty, less overall participation New Power Values Informal (networked) governance, opt-in decision-making, self-organization Collaboration, crowd wisdom, sharing, open-sourcing Radical transparency Maker culture, "do-it ourselves" ethic Short-term conditional affiliation, more overall participation
