From: Towards a theory-driven research agenda in six sigma quality innovation: linking research opportunities with organization theory typology

Issues

SSQI & TQM

Integration

- Which factors in SSQI enable its integration with the business strategy?

- How can SSQI be integrated with administrative or service processes?

Leadership

- Is the nature of top management’s support for Six Sigma initiatives fundamentally different from their support for TQM initiatives? What are the reasons for the difference?

Fuzziness

- What are the factors that contribute to the fuzziness of TQM?

- Integration of practices and philosophies professed in TQM literature with Six Sigma.

Goal-orientation

- What are the feedback mechanisms to dynamically adapt Six Sigma goals with changing conditions?

Use of tools

- Impact of “quality purism” on TQM success.

- Implications of technical zealotry in Six Sigma implementation.

Cross-functional orientation

- Cross-functional collaboration in Six Sigma vs. departmentalized approach in TQM.

“OR” vs. “AND” orientation

- What are the unique governance mechanisms in Six Sigma that enable firms to undertake both small improvements (as in TQM) and major process redesigns (as in re-engineering)?

Training

- What is the significance of context in Six Sigma training?

Focus

- What is the evolutionary nature of focus of Six Sigma project goals?

Issues

SSQI Readiness Level

Strategic intent

- Six Sigma implementation as a proactive means for improving competitive position vs. Six Sigma as a reactive strategy to stave off future disaster (e.g. the case of Motorola).

- Six Sigma readiness indicators for a proactive and a reactive approach.

Relationship with implementation success

- What is the relationship between Six Sigma readiness level and Six Sigma implementation success?

- What is the relationship between number of Six Sigma projects implemented and Six Sigma readiness level of a firm?

Issues

Top Management Support

Role of top management

- Top management’s role in supporting: (i) the development of a strong rationale for Six Sigma; (ii) for setting clear objectives and, (iii) for continued Six Sigma initiatives.

- Top management’s role in instituting “hard” measures to gauge the impact

- Top management’s role in ensuring accountability at all levels.

Rewards, penalties & motivation protocols

- Rewards and penalties for successful Six Sigma implementation.

- Mechanisms for communicating favorable as well as unfavorable results and for maintaining the momentum towards Six Sigma quality.

Issues

Choice of Appropriate Metrics

Integration & Aggregation

- Integration of Six Sigma measures with observed data.

- Integration of continuous and discrete measures of performance.

- Mechanisms for streamlining the process for measurement for effective and efficient Six Sigma implementation.

- Aggregation of metrics at different organizational levels.

- Integration of Six Sigma project metrics with the real or perceived reward structure.

- Tradeoff between richness and complexity of Six Sigma metrics.

Theoretical issues

- Links between process-based view of SSQI and the resource-based view.

- Dynamic evolution of Six Sigma process measures of performance.

- What is the “metrics typology” of SSQI?

Strategic & Operational Intent

- Fit between Six Sigma metrics system and the strategic intent of a firm.

- How is the rotation or change in Six Sigma metrics associated with the dynamics of demands placed on the operating system?

- What is the level of consistency among the set of Six Sigma metrics used in an organization? What is the level of consistency between the Six Sigma metrics and the corporate strategy? How is consistency related to performance?

Cross-functional collaboration

- Role of Six Sigma process metrics in fostering cross-functional and inter-firm decision-making.

- How should Six Sigma metrics be designed so that they reflect the interdependencies of different functional areas and interconnected firms in a supply chain?

Measure validation and relatedness

- Relationship between financial and operational measures

- Measures to capture the cost of poor quality

Constraints & bottlenecks

- What are the constraints in moving from traditional measures of performance to Six Sigma process measures of performance?

Issues
