Lean Six Sigma—A Management Tool for R&D Teams to Improve Quality and Efficiency

With the rapid development of the domestic software industry, software quality control has gradually become the focus of major R&D enterprises. It is a common demand of R&D enterprises to guarantee the delivery quality of complex software and improve the efficient collaboration of R&D project teams. In order to solve this problem, more and more R&D enterprises are trying to introduce the Lean Six Sigma management methods into R&D projects to quickly improve the level of software development and project management.

I. What is Lean Six Sigma?

Lean Six Sigma (LSS) is not a stand-alone management model but a Lean Production and Six Sigma management model. The Lean Six Sigma management aims to achieve better management results by integrating Lean Production and Six Sigma management, absorbing the advantages of both models, and compensating for the shortcomings of the individual production models.

As a project-based organizational management model, Lean Six Sigma helps enterprises find the optimal solution for profit and quality by continuously exploring improvement opportunities and carrying out continuous project improvements. The software industry has an inherent advantage in introducing Lean Six Sigma because people in the technology and software industry generally have better logical thinking ability and will be more proficient in learning and applying Lean Six Sigma, which will produce better results.

II. The Significance of Introducing Lean Six Sigma into R & D Enterprises

Essentially, Lean Six Sigma is a process quality goal where sigma is a statistical measure of process variability. Lean Six Sigma is not about averages but variance or fluctuations. In order to improve variances, enterprises need to disassemble their entire R&D chain, including R&D, marketing, service, etc. The goal is to eliminate everything that could lead to waste, inefficiency, and unpredictable situations that could lead to customer complaints.

The core idea of Lean Six Sigma is DMAIC, which means: Define, Measure, Analyze, Improve and Control. It focuses on improving the entire project by combining Lean thinking with Six Sigma tools, mainly for complex R&D problems and projects. It focuses on turning all the work into a process, using quantitative methods to analyze the factors affecting quality and identify the most critical factors for improvement, thus achieving higher customer satisfaction.

III. The Five Phases of Lean Six Sigma DMAIC Activities

1. Definition Phase - D (Define)

Combining lean production management with six sigma management tools and managing the current situation through data analysis. The work includes setting up a project team, analyzing customers' critical needs, identifying product requirements or project processes, formulating project plans, determining the key influencing factors of quality, defining the scope of the project, etc.

2. Measurement Phase - M (Measure)

The primary purpose of the measurement phase is to collect data, confirm problems and project conditions and quantify them; Second, to sort out the data to provide clues for finding the reasons and ensure the accuracy of the quoted data in the whole process.

3. Analysis Phase - A (Analyze)

Using Six Sigma technology and lean flow principle to analyze variation and waste, determine the critical influencing factors affecting products or R & D projects through data analysis, and accurately eliminate non-critical elements.

4. Improvement Phase - I (Improve)

This phase is based on the principles of flow and pull, where processes are added, rearranged, deleted, simplified, and merged, while specific process stability and implementation processes are improved. We should eliminate or reduce the impact of non-critical factors and optimize the resolution mechanism for critical issues to minimize quality problems.

5. Control Phase - C (Control)

In addition to completing the Six Sigma management control content, new issues arising from the implementation are summarized for the next improvement cycle. We have to standardize improvement results, revise documents, update lessons learned and other methods to standardize successful experiences, monitor process control, maintain improvement results, share experiences, and expand the scope of application.

Overall, after introducing Lean Six Sigma management into an R&D company or project team, the team's R&D product or project, by strictly following the above five phases of DMAIC, can effectively achieve breakthrough improvements in R&D product quality and project management. From the statement, problem analysis, and solution of a project, through Lean Six Sigma DMAIC process activities, team members can play the most influential role, cooperate effectively to complete the project, and eliminate process defects and non-value-added processes on time, thereby improving software R & D quality and service, reducing costs, shrinking project cycle, improving customer satisfaction and enhancing enterprise competitiveness.

IV. Notes

R & D enterprises or project management teams should pay attention to the following points in the process of introducing Lean Six Sigma Management:

• Lean Six Sigma is not a simple addition of Lean Production and Six Sigma but a complementary, well-integrated combination.

• The introduction of Lean Six Sigma is a process of continuous practice, accumulation, and optimization of enterprises, which can not be achieved in one step.

• Lean Six Sigma is not a universal tool and needs to be combined with the enterprise's characteristics. For the actual problems in software development and project management, we must first understand the root causes and analyze specific issues to avoid unnecessary losses caused by copying others' experiences.

V. Conclusion

In today's rapidly developing software R&D industry, how to effectively combine Six Sigma continuous improvement methods with Lean management methods to quickly improve the fine control of enterprises and enhance software quality is a question that every R&D team needs to explore constantly.
