Strong project management practices are vital to a Six Sigma project’s success. Without these practices, a project will often creep. Its scope will change, the time required to implement changes will increase, and understanding of the requirements will falter.

A good project manager keeps an eye on all of the variables and controls them.

Discipline equals freedom.


Who Manages a Six Sigma Project?

In Six Sigma project management, senior managers take an active role. They create projects by choosing a business process that is in need of improvement. However, a project manager – often a Six Sigma Black Belt – will usually lead the project itself.

Project Management Stages

There are three basic stages in Six Sigma project management:

  • Planning: You work out what needs to be done to make the project a success.
  • Scheduling: You map out how much time it will take your team to complete all the tasks.
  • Controlling: You keep track of both of these factors throughout the project, and adapt resources, planning, or scheduling so that it stays on track.

Stages differ from project management phases because they aren’t limited to a specific point in time. You’ll find yourself planning, scheduling, and controlling a project all the way through it.

Project Management Phases

Each Six Sigma project has five basic phases. These are discrete, meaning that as one phase ends, another begins. Contrast this with the project stages, which occur throughout the project.


This is where you put together the vision for the project. You work out what it’s supposed to achieve and why. You talk to stakeholders. And you sell the project.

A common issue that Six Sigma projects face is a lack of business impact for the company. Quantify the bottom line benefits the project will achieve. as well as the tactical metric improvement.


You have a high level vision, and you’ve received approval to move ahead. Your next job is to move down one level and look at what you’ll need to achieve that vision. In this phase, you decide the scope of the project. You need to answer questions like:

  • What will you actually deliver?
  • Who will work on the project?
  • What are the requirements?
  • When does it need to be completed?
  • What resources will you need?
  • What’s your budget?

This is the phase in which you’ll develop the project charter.


If the planning phase is all about the what, the designing phase is all about the how. In this phase, you look at your deliverables. You answer questions like:

  • What do our deliverables (outputs) actually look like?
  • How will we measure the quality of those outputs?
  • How will we monitor our progress?
  • When and how will we report project status to stakeholders?
  • How will we create our deliverables?
  • What will our processes look like?
  • What’s our schedule for the project?


Once you’ve figured out the what and the how, you’re ready to start implementing the project. Use the design documents to develop your deliverables. Monitor progress of the development. Measure outputs using the metrics you decided on.


Once your development work is done, you need to wrap it up. This includes steps like:

Project Management Phases vs DMAIC

You might have noticed a distinct similarity between the phases mentioned above and the DMAIC phases. It’s no coincidence – the two models have a lot in common. Where they differ, though, is in their purposes. DMAIC is a process improvement cycle. It’s often used as a tool in developing and planning projects. It’s not, however, used to manage projects. That’s why the project management phases don’t match perfectly with the DMAIC cycle.

Project Management Tools

You have a lot of tools available to use in managing a project. There are dedicated planning tools and tracking tools, as well as analysis and design tools. We’ve listed some of the most commonly used.

The ASQ offers a few project management resources. You’ll need to be a member to view some of the content.

George Eckes

George Eckes has written several books around Six Sigma. They’re renowned for being clear and easy to read, while giving the reader some incredibly useful information.

Common Six Sigma Project Management Questions

How long should a Six Sigma project take?

According to George Eckes – 120 days.

What is the main disadvantage of presenting a team with a project > 160 days?

There’s a lowered expectation of success according to Eckes.

What are the Deliverables of a Lean Six Sigma Project?

Each phase of a Lean Six Sigma project has different deliverables. While there are variations on each project as each project requires the use of different tools, there are similarities.

At minimum you should have a project charter to start off with. A Stakeholder communication plan is also essential from my experience.

Additionally, I like to schedule regular reviews with my stakeholders on a predictable schedule and certainly with the achievement of a milestone. Your frequency of meeting with your stakeholders will depend upon the nature of your work and their involvement. At the least I would review the conclusion of each DMAIC phase with them to achieve sign off.

Hi Abdul,

Yes, it does. We moved the commitment scale article to be part of the communication plan. People have been complaining about too many articles so we are combining similar concepts across the board. You’ll find what you need there.

Best, Ted.
