Presenting a summary of the critical elements and corresponding actions for building a Lean Six Sigma infrastructure in an organisation:
Phase 1: Creating visibility and awareness on the key concepts of quality and six sigma
Start with the WB and YB training sessions with the operations staff and assisting them to complete their respective projects. Also share regular learning snippets on the 7 QC tools via internal communications emails to create more awareness on quality and continuous improvement.
Phase 2: Highlighting the achievements of the WB and YB projects
Showcase the achievements of these projects in top management forums. Getting a buy in from them to carry out similar activities in all their departments. Also present case studies demonstrating cost savings and quality improvements achieved by other organizations through Lean Six Sigma initiatives.
Phase 3: Assemble a team of lean six sigma trained staff
Create a team and train them in cross functional improvement projects. Focus on reducing defects or improve on efficiency.

As an MBB, I have been given responsibility for creating the LSS infrastructure in my company. The following are the critical elements I will pay particular attention to:


1) Leadership support - I will assist leadership in understanding Lean Six Sigma as the necessity for ongoing development in the workplace to help achieve corporate objectives.


2) Create a work plan - I'll put together a plan of action that outlines the scope of the improvement, taking into account resource changes, process modifications, and project funding.


3) Build the team – As an MBB, I will train high-performing designated employees for the role of GB or BB and if required will hire external consultants to develop my team in order to improve process performance


4) Determine Responsibilities - In accordance with the defined work plan, I will allocate ownership to each BB to focus on a particular area.


5) Focus on consumer needs and establish CTQ - Respective BBs must find creative improvement suggestions based on client specifications that will reduce waste and boost process effectiveness.


6) Drive improvement initiatives - As an MBB, I will instruct all BBs or GBs on how to apply problem-solving techniques to develop and carry out an action plan for crucial variables affecting dependent variables.


7) Create control plan to sustain improvement – For each of the project being driven, a full proof control is created to maintain the improvement in the process


8) Evaluate the performance - Post improvements, I will evaluate KPIs to show the leadership on the contribution of improvement projects towards achieving business goals

  • To understand the level of LSS requirement, number of functions it needs to roll out, budget and resources requirements. 
  • E.g. In a contact center check requirement for LSS in BUs like WFM, Quality, MIS, Operations, Training etc. Then understand how many YB, GB or BB level champions required. Take all the details and make a proposal.


Leadership Approval & Commitment:

  • Present the business case for requirement of LSS methodology rollout to the leadership. 
  • Get approval for required budget, resources & senior management commitment to help drive.
  • E.g. Get budget approval for LSS training at required level from YB to BB. Set expectations on number of projects etc. Set expectations to commit for regular meetings and governance of the whole roll out.



  • Another assessment to understand the rollout level of requirements and then plan further by creating actions with timelines.
  • E.g. Create LSS champions, Create suitable training programs, set project selection plans, create an R&R program etc



  • Roll out comms to explain the coms across the organisation, so everyone is on board.
  • E.g. Email comms to explain the plan followed by briefings to explain it further and to encourage people to participate.



  • Train the champions first on LSS.
  • High level meets with all the champions to understand respective processes and gather data.
  • Recognise all improvement opportunities and follow selection criteria to finalise projects.
  • Try to combine or assign multiple YBs under a GB and multiple GBs under a BB projects that way it's a collective effort which should further help create that LSS culture across the board.
  • Create a feedback mechanism from all stakeholders.
  • Set regular rhythms for continuous improvement opportunities so it's and habitual in future.



  • Conduct post implementation review to measure success.
  • Understand improvements required in the roll out & support required.
  • Create SOP for L&D and final handover.
