The context
The Minnesota Pollution Control Agency provides a useful public-sector example of improvement becoming an organisational capability. EPA’s account describes 21 agency Six Sigma projects covering regulatory and administrative processes, supported by internal practitioners and leadership training in Working Smart for Environmental Protection.
This is an independent analysis of that documented deployment through a Master Black Belt lens. The sources identify agency leaders and trained practitioners, but do not identify a designated Master Black Belt. The programme responsibilities below are an interpretation for training purposes; proposed governance practices are distinguished from reported actions.
The problem
Wastewater permitting supplies the concrete starting point. Only 9.42 percent of permits were issued within 180 days in 2003. The team set a target of 90 percent by December 2005, according to EPA’s wastewater permitting case study.
At programme level, that creates several connected questions. Which delays deserve scarce improvement capacity? How should technical specialists divide time between casework and redesign? What evidence would justify transferring a successful practice into another permitting process? A local turnaround target leaves those deployment decisions unresolved.
Scoping the Master Black Belt assignment
A suitable assignment would cover the agency’s permitting improvement portfolio, with links to supporting administrative processes. Black Belts would own individual project charters. The Master Black Belt would shape project selection, coach practitioners, review evidence and establish how process owners sustain improvements.
The scope would include common measurement definitions, resource allocation and escalation routes. Technical review quality and public participation would be explicit constraints. A portfolio selection matrix could weigh public-service impact, environmental risk, delay burden, data readiness and available sponsorship. Projects dependent on the same specialists would need sequencing.
Minnesota’s experience supports taking scope seriously: EPA reports that the agency narrowed projects to make implementation faster and more manageable in its discussion of project boundaries. My interpretation is that portfolio governance should preserve that discipline as demand for improvement grows.

The tools applied phase by phase
Define: connect customer needs to project selection
The wastewater team interviewed internal and external customers and aligned priorities across functional areas, as documented in EPA’s case study.
A Master Black Belt could translate that approach into a common charter template. Each proposed project would state its service problem, affected stakeholders, process boundaries and accountable sponsor. Selection discussions would also include citizens and environmental interests, alongside applicants. A faster decision has public value only when the decision remains sound.
Measure: establish comparable evidence
Minnesota introduced staff time tracking and a review process for application completeness, according to the documented process changes.
For portfolio oversight, I would add a shared measurement dictionary: when elapsed time begins, what counts as completion, how withdrawals are treated and which cases enter each denominator. Coaching would include reviewing actual case records with Black Belts to test consistent classification. Reporting would separate construction and non-construction cases, while retaining visibility of waiting time experienced by applicants.
Analyze: distinguish shared causes from local variation
The wastewater project used a risk matrix to determine appropriate review depth for different applications, as described by EPA.
At deployment level, process maps and stratified lead-time analysis would help test whether delays arise from shared approval routes, incomplete submissions or specialist capacity. The Master Black Belt’s coaching question would be: does the evidence support a common intervention? Similar-looking queues may require different remedies. Any statistical comparison would need attention to case complexity and changes in workload.
Improve: build capability alongside process changes
Reported wastewater changes included permit-writer manuals, formal mentoring and a forum for resolving issues with senior staff in the case study. At agency level, EPA recorded four certified Black Belts and 183 certified Green Belts in its deployment account.
A Master Black Belt assignment would connect training to live project demand. Joint evidence reviews, observed facilitation and feedback on analysis would make coaching assessable. Replication decisions would consider local conditions, ownership and implementation capacity. Training completion alone would leave those questions open.
Control: govern the remaining gap
For this portfolio, I would propose a control plan for every transferred process: an owner, measurement frequency, response triggers and an escalation route. The review pack would show ageing open cases alongside completed-case performance, preventing difficult unfinished work from disappearing from view.
Project status would also distinguish implementation completion, demonstrated improvement and target attainment. A process owner could accept a functioning control plan while the sponsor authorises further work on a remaining performance gap.
What the results establish
Wastewater permits issued within 180 days rose to 75 percent in 2006, although the original 90 percent target remained unmet, according to EPA’s reported results. Elsewhere in the portfolio, air construction permits issued within 150 days increased from 33 percent to 75 percent in the agency summary.
These are substantial reported service improvements. The cited summaries do not provide the underlying case-level time series needed to independently test stability or attribute each gain to a particular intervention. I would retain that limitation in any benefits review and avoid combining different permitting measures into one agency-wide improvement percentage.
What a trainee should take from it
A useful trainee exercise is to prepare the sponsor’s next portfolio review. The wastewater result leaves a genuine decision: extend the existing project, commission a narrower follow-on investigation or monitor the revised process while gathering more evidence.
The submission should explain what additional data would change that decision, which Black Belt needs coaching, and which process owner would carry the control plan. It should also identify an attractive project to defer because its demands exceed available specialist capacity. That decision exposes the practical judgement involved in managing the whole programme.
