Any building development undergoes two major phases. One is the conceptual design stage and the other is the actual construction phase. In both phases, there is great opportunity for cost savings, improved functionality and improved speed.  Lean methodology focuses on the optimizing the shareholders capital and ensuring that functionality and cost effectiveness of building design is optimized. It also ensures that there is minimum cost and time variance in construction and variance at completion is minimal and perhaps positive – ie under budget and within deadlines.

At the design stage, brainstorming and focusing on the 80:20 rule, can deliver significant scope for reassessing specific areas of the project and bringing in solutions that offer lower cost with perhaps even better functionality thereby increasing  the value to shareholders and to the end customer.

The Lean method also enables a focus on the greatest efficiency in all characteristics of operations in the actual construction process.  Lean strategy focuses on identifying better solutions and removing wasteful steps that unnecessarily consume effort and resources. Through the use of Six Sigma as well, there can be additional stability in the construction processes such as delivery, approvals, payments, ensuring a smooth flow in operations. These two methodologies can deliver savings of up to 30% of the project value.

Through QServe Qatar, we can offer Lean Solutions based on accredited IASSC Standards (USA), through a collaborative approach to planning and implementation to achieve the following:

  • Ensuring lean solutions are implemented at the design stage
  • Reducing  rework, wasted material, tools and equipment in the construction phase
  • Eliminating  the Eight forms of Lean Waste
  • Enabling work flow so that crews are more productive
  • Improving  Visual Management
  • Ensuring  Best practice implementation
  • Building  “Look ahead schedules “
  • Instilling  Continuous  improvement
  • Minimizing  overall project durations


Lean Six Sigma certification has an introductory level which is White Belt, and then three internationally recognized levels of difficulty and experience, known as Yellow Belt, Green Belt, and Black Belt.  The Yellow Belt is the initial compulsory level as it incorporates the basic foundation of Lean and Six Sigma knowledge.

Roles which might benefit from Lean Six Sigma certification include:

  • Business Process Manager
  • Team Leader
  • Supervisor
  • Manager
  • Senior or General Manager
  • Program Manager or Project Manager
  • Analyst or Business Analyst
  • Continuous Improvement Manager
  • Quality Assurance Manager

White Belt certification introduces you to identifying Lean waste and provides a few tools. It is good for to introduce a few basic concepts to those who may not wish to proceed further with Lean Six Sigma.

Yellow Belt certification is an efficient way to learn the basics of Six Sigma. It is ideal for those who need to lead limited improvement projects and for those who are supporting larger improvement projects in a limited role in a Six Sigma team.

Green Belt certification is ideal for those who are part of a Six Sigma Management Team. Ideal for those who are assisting with data collection and analysis for improvement projects. Green Belt training will allow them to implement Lean Six Sigma proficiently.

Black Belt certification is for team leaders who manage big improvement projects. It also helps in problem-solving projects. At the Black Belt level, they will have a thorough understanding of all aspects of Lean Six Sigma

The impact of Six Sigma can be seen   in a company at every level. With the Six Sigma certification, staff will have the knowledge to identify the characteristics of an organization’s business processes. They will be able to measure, analyze, control, and improve them. They will also have the capability to conduct a review of current processes and gain a very clear knowledge of their impact on cost and quality.
