What You Need to Know About Lean Six Sigma

Advice

Often customers want to know, where shall I start using Lean Six Sigma?  How can I go from my current level to Six Sigma?  The answer is simple.  It requires the organization to listen to their customers, document what they are hearing, and prioritize the major themes they hear from customers.  Six Sigma doesn’t have to be complicated, organization-wide or address every problem the organization has at the on-set.  Begin simply by asking these questions:

Where is the biggest pain? Start here!  Pain can be further described as follows:

Customers are complaining.

Cost is substantial / problematic.

Known problems are easily described.

Previous improvement efforts have failed to achieve the desired impact.

Next, the organization must ask itself - Where are our most talented resources?

Lean Six Sigma spreads when people see with their own eyes the success it can allow teams to achieve.  Therefore, picking projects that have the highest likelihood for success becomes critical during the early stages of Lean Six Sigma implementation.  Ask where do we have the best:

Leaders

Effective teams that work well together

Analytical resources who are interested in working with innovative teams.

Even terrific teams can fail if their leadership does not support the effort, or if the effort doesn’t address one of the key leadership priorities/initiatives.   Have you set your team up for success?

In which Agency/Organization is the top leadership willing to try Six Sigma?

  • Effective teams who work well together and are supported by strong leaders should be the first ones selected for a Lean Six Sigma project.
  • These types of teams will ensure early wins so as to convince others of the benefit of the Lean Six Sigma approach.
  • See this Wall Street Journal article, https://www.wsj.com/articles/why-companies-should-hire-teams-not-individuals-1509329580, “Why Companies should hire teams not individuals”, Sydney Finkelstein, October 29th 2017. Business Section.  Journal Reports: Leadership.

Go where the energy is highest!

Finally, in order to complete the project in a short period of time, ask this: Where do you have significant data already that would lead to effective project selection?  When new data must be gathered to start a project, it requires experienced, skilled analytical people who have probably used Lean Six Sigma before.  Wait until your organization has some experience, or use external resources to accomplish this data collection exercise first before you undertake an initiative in this area.  Otherwise, ask yourself, “Where do we have either:

Scorecards, Dashboards or Metrics that are available and utilized.

Six Sigma process improvement efforts are accomplished project by project. All successful projects require structure – a team, a leader and a sponsor/champion.  If projects are not defined up-front, teams have difficulty scoping the opportunity and attacking it.  Champions have difficulty supporting the effort.  In order to define a project – start with these questions:

  1. Is this project central to the organization’s goals and objectives?
  2. Who is the customer or customer segment who will most directly benefit from the project’s execution? Will the customer feel differently if the goals outlined in a project charter are achieved?  A customer can be an internal (to the organization) one - the external customer is not always the right one for your project.
  3. Will the executives responsible for this project and the resources dedicated to its completion feel accountable for its success?
  4. What is the project scope and can this project scope be executed in 4-6 months?
  5. Will this project deliver quantifiable results?
  6. If data that describes the problem is not readily available, will it be available to be gathered within the first 1-2 months of the project?
  7. Is there an identified process owner who will take over the improvements implemented in the project and own the ongoing control plan documented during the control phase?
  8. Are the appropriate team members/resources available to ensure this project is successful?

Unfortunately, the annals of history include thousands of projects that either failed, were stopped or never achieved their full potential.  Why is this the case?  There are several reasons that are sure to lead to project failure.  These include:

  • Lack of defined project scope or project scope is too great. Experienced Lean Six Sigma Master Black Belts or Black Belts can assist leaders in avoiding this by spending time defining a scope that can be executed in 4 months, given the current team’s availability.
  • No results-orientation or ownership for implementing solutions. Stakeholder objectives and involvement must be identified and documented using a project chartering effort which creates support and fleshes out potential barriers to success.
  • No pulsing mechanism is used to gather team on a weekly basis. This is a project requirement and must be enforced by the project leader and encouraged by the project champions and sponsors.
  • No pulsing mechanism is used by the champions/sponsors to find out project status: Lack of leadership involvement in updates can result in projects which crawl towards the finish line, many of which fall short of reaching it.
  • Risk assessment not used to identify risk factors to be managed. A proper risk assessment should be conducted in both the project chartering and the improve phase to ensure team has thought through most likely and impactful risks and has an abatement plan to address these.
  • Early project findings (typically discovered in measure phase) identify issues that the leadership team is unprepared to address. Sometimes projects identify uncomplimentary customer perspectives.  This situation can necessitate a response that the organization is unwilling to support.  The lean six sigma team should not be penalized for this situation but rather encouraged through effective leadership which gives political support to the project effort or selects another opportunity for the team to address.
  • Organizational priorities change and sufficient time cannot be allocated to the project effort. The organization must be honest about its priorities and if these no longer include the Lean Six Sigma project, the team should be released or reassigned.
  • Project leaders views themselves as facilitators who are not responsible for implementation. This responsibility should be set during the project chartering phase when the champion and the project leader/team discuss the role of the team.  There are project efforts which do not require implementation, but these are rare and are likely focused on providing the data to support future projects.  More likely, the team will be responsible for all phases of the project and transition ownership to the process owner during the control phase.
  • Team has hidden agendas which are not discovered or addressed during project evolution. Every project team will go through the forming, storming, norming, and performing phases of team work (See Bruce Tuckman’s 1965 Model re: stages of group development).  During the forming and storming phases, these issues should be raised, conflict addressed, and norms determined so that the team can be most effective moving forward.  Practiced teaming skills are a significant requirement of Lean Six Sigma projects and facilitating teams is one of the most critical skillsets of a project leader.
  • Team not given enough time to be successful. The longer a team works together, the more successful they can be. High-energy, achieving teams have learned the value of conflict resolution, team norms and project team charters.  They effectively use ground rules to encourage honest dialogue and supportive team behavior.  The more quickly a newly-formed team can move through the stages of team evolution, the more swiftly they will be capable of driving project results.

  1. Defined data-driven methodology used to approach problem

DMAIC

14 Required Deliverable Tollgates

Define Phase - Deliverables

Define 1: Project CTQ’s – Critical To Quality Characteristics.  The first deliverable starts the project off with a focus on the customer as the team uses Voice of the Customer techniques to document the customers’ CTQ’s.

POLICE

Define 2: Approved Charter.  Next the team must identify all project stakeholders to develop a project charter which will determine the project’s focus, timing, goals, business case, core and extended team members and sponsoring leadership.

Define 3: Process Map.  Early in the project’s life, the team will document a high level view of the process which details the series of steps required to execute the process.  The map will also include the process’: customers, suppliers, inputs required and output(s) delivered to the customer.

BOARD

Measure Phase - Deliverables

Measure 4:  Project Y & Performance Standards.  The measure phase commences with a selection of the metric(s) that most directly reflects the customers’ CTQ(s).   This metric is known as the Y variable.  Customers and key stakeholders will be consulted to determine acceptable performance standards for the Y metric.   This performance standard will enable the team to determine what is a ‘defect’.

Measure 5:  Data Collection Plan & Validated Measurement System.  The key output of the measurement phase is a baseline of the current process’ performance.  Teams must document their approach to data collection and validate that their measurement system does not introduce significant variability simply in the way the data are being gathered.  With this required deliverable complete, the team can be assured that their measurement baseline accurately reflects the actual process.

Measure 6:  Data for Project Y.  The team gathers the data to baseline their process’ current performance.

Measure 7:  Process Capability for Project Y.  This deliverable is a statistical calculation based upon the data gathered in deliverable six.  It is a measurement of how many defects are generated in their current process out of the total opportunities to create a defect.  Process capability provides the baseline measurement against which future improvement efforts will be assessed.

Measure 8:  Improvement Goal for Project Y.  The last deliverable of the measure phase ensures that the team sets a goal that reflects the project charter and is also based upon current performance.

Analyze Phase - Deliverables

Analyze 9: Prioritized List of All X’s.  As the team begins the analyze phase, they will gather all information from the Define and Measure phases and will also utilize additional tools to identify a complete list of root causes which are driving performance in the Y metric.  These root causes are termed “X”’s in Six Sigma terminology.

Fishbone diagram - many uses in the manufacturing industry.

Analyze 10: List of the Vital Few X’s.  The team will continue to work with the list of X’s, evaluating each one to determine if it is a ‘vital x’ driving a significant proportion of the defects in the Y metric.  If the X is proven to be a ‘vital x’, solutions will be developed to address this X in the Improve phase.  If the X is determined to be a ‘trivial many’ X, in other words it is not driving a significant percentage of the variation in Y, it will be documented but not pursued in the Improve phase.

Improve Phase - Deliverables

Improve 11:  Proposed Solution.  The Vital Few X’s will advance to the first deliverable of the Improve phase as the team determines what strategy to use to develop proposed solutions which will address each of these X’s.  Alternative solutions will be considered, and the best will be selected and prepared for pilot.

Improve 12:  Piloted Solution.  The piloted solution is a process improvement that has been tested on a small scale in a real business environment. A successful pilot is one in which the piloted solution meets the project performance goals (and the ‘musts’ criteria).

Control Phase - Deliverables

Control 13:  Sustained Solution.  A sustained solution is a fully implemented and statistically confirmed process improvement that is supported with a control plan to ensure it remains in place over time.  For a solution to be sustained, a control plan must be put in place which addresses each Y and vital X.

Control 14:  Project Documentation.  Documentation is a necessary step to ensure that the learning gained via improvement is shared and institutionalized.  By doing this, the team will cement the gains of improvement as well as build supporting organizational systems and structures for future projects.
