5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Project Scope & Methodology Follows defined methodology, escalates scope changes. Chooses appropriate methodology for routine projects, proposes minor scope adjustments. Defines project scope for complex, ambiguous problems. Selects and adapts methodologies (e.g., DMAIC, Lean, DOE) for maximum impact. Consults Master Black Belt on strategic alignment.
Resource Allocation (Team/Budget) No authority. Works within assigned resources. Manages own time and project-specific resources. Requests additional resources from manager. Allocates resources for their direct team (3-8 reports). Manages project budgets up to £50K independently. Consults Master Black Belt for budgets between £50K-£500K. Significant input on hiring for their team.

Leads and approves significant, cross-functional process changes. Accountable for change management and sustainment plans. Requires sign-off from relevant functional VPs for major operational shifts.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Project Portfolio Value Delivered
The total validated financial savings or revenue uplift from the projects you lead and oversee.
Target · Deliver £500K - £1M in auditable annualised savings or revenue impact.

Leading a project that reduces raw material waste by 15%, saving £250K annually, and another that improves order fulfilment accuracy, leading to £300K in avoided penalties.

Operational Efficiency Improvement
Measurable improvements in key operational metrics like OEE (Overall Equipment Effectiveness), throughput, or cycle time across your areas of influence.
Target · Achieve a 5-10% improvement in targeted operational KPIs year-on-year.

Increasing OEE on a critical production line from 75% to 82% by optimising changeover times and reducing unplanned downtime, or cutting order-to-delivery cycle time by 10%.

Team Development & Mentorship
The growth and certification of your direct reports (Green Belts and analysts) and their ability to lead their own projects.
Target · Mentor and support 2-3 Green Belts to successful project completion and certification annually.

Guiding a Green Belt through their first complex DMAIC project, resulting in their certification and a £100K saving for the business, while also providing regular coaching sessions.

Deployment of New Methodologies/Tools
Successfully introducing and embedding new process improvement tools or advanced analytical techniques within Operations.
Target · Pilot and embed 1-2 new methodologies or digital tools annually, with documented adoption and benefits.

Leading the successful pilot of a process mining tool on a key logistics process, identifying £150K in hidden rework, and then training the wider team on its use.

Strategic Problem Solving

  • You're regularly sought out for advice on complex operational issues. Your project charters demonstrate a clear understanding of strategic business objectives. You anticipate potential roadblocks and proactively plan for them, rather than reacting.
Influence & Buy-in
How effectively you gain support and commitment from senior leaders and cross-functional teams for your projects and proposed changes.
  • Stakeholders actively participate in your project reviews and champion your solutions. You can present complex data simply and persuasively to different audiences. You're seen as a trusted advisor, not just a technical expert.
Team Leadership & Empowerment
Your skill in guiding, developing, and empowering your direct reports, fostering a culture of continuous improvement within your team.
  • Your team members consistently meet project deadlines and deliver high-quality work. They feel supported and challenged, and show clear growth in their capabilities. You delegate effectively, giving others opportunities to lead and learn.
Proactive Risk Management
Your foresight in identifying potential operational risks or process failures and implementing preventative measures before they become major issues.
  • You regularly conduct FMEAs on critical processes. You identify 'special cause' variations early and implement effective control plans. You're seen as someone who thinks several steps ahead, not just reacting to the immediate problem.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Big, Messy Problems

You get a real buzz from taking a complex, ambiguous operational challenge that's impacting the business and systematically breaking it down with data, then seeing your solution actually work.

Tackling a persistent quality issue that's causing £1M in annual scrap, diagnosing it through DOE, and implementing a fix that reduces it by 80%.

Driving Tangible Impact

You're not satisfied with just analysis; you want to see your recommendations implemented and deliver measurable improvements to the bottom line or customer experience. You want to see your work make a difference.

Seeing a new process you designed reduce customer complaints by 25% or cut operational costs by £500K, and knowing your fingerprints are all over it.

Developing Others

You enjoy guiding and mentoring junior team members, helping them grow their skills, and seeing them successfully lead their own projects. You're a coach at heart.

Helping a Green Belt navigate a tricky stakeholder situation on their project, then watching them confidently present their findings to senior leadership.

What frustrates people
  • You'll rerun the same analysis three times because stakeholders keep changing the question or moving the goalposts. The 'urgent' request that disrupted your Thursday will get deprioritised on Friday, or worse, completely forgotten.
  • You'll build a beautiful model or design an elegant process that never quite gets deployed because the business moved on, or a political roadblock appeared. If you need to see every piece of work make it to production, you'll struggle here.
  • Dealing with 'garbage in, gospel out' data. You'll spend 60% of your project time cleaning and validating data from poorly managed ERP systems, only to have stakeholders question the findings because they don't trust the source data.
  • Watching the hard-won gains from your project evaporate over 6 months because the operational managers failed to enforce the new standard work and control plan. The 'control phase' often feels optional to others.
  • Presenting a data-proven solution that gets vetoed because it challenges a senior leader's pet project or a department's established power structure. It's not always about the data; sometimes it's about power.
  • The recurring challenge of explaining concepts like confidence intervals and p-values to senior leaders who just want a 'yes' or 'no' answer, often oversimplifying complex realities.
What this role does not give you
  • A quiet, predictable, solo analytical role. You'll be out on the floor, in meetings, and coaching your team.
  • Direct authority over all resources. You'll need to influence and persuade, not just command.
  • Immediate gratification on every project. Some changes take months, even years, to fully embed.

8Who you work with

Your work directly shapes the operational efficiency and quality across significant business areas, often influencing how we design new processes or even how we think about our entire supply chain. You're not just fixing problems; you're helping to build a more robust, future-proof operation.

Inside the business
  • VP of Operations
  • Production Managers
  • Logistics & Supply Chain Leads
  • Quality Assurance Managers
  • Finance Business Partners
Outside the business
  • Key Suppliers (for process integration)
  • Technology Vendors (for new tool evaluation)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A certified Six Sigma Black Belt with at least 5 years of experience leading complex, cross-functional DMAIC projects.
  • Demonstrable experience mentoring or guiding junior analysts or Green Belts on continuous improvement projects.
  • Proven track record of delivering significant, quantifiable financial or operational benefits through process improvement initiatives (e.g., £250K+ in annualised savings per project).
  • Strong experience presenting project findings and recommendations to senior management and influencing decision-making.
  • Advanced proficiency in statistical analysis software (Minitab or JMP) and data visualisation tools (Power BI or Tableau).

10What to practise next

Where the job is going, and what to do about it starting this week.

Process Mining & Simulation Software

Traditional process mapping is great, but process mining tools (like Celonis, UiPath Process Mining) automatically uncover the 'as-is' process from system logs, highlighting hidden rework and bottlenecks. Simulation tools then let you test 'what-if' scenarios before implementing changes, drastically reducing risk and accelerating the 'Improve' phase.

Event Log Data Extraction · Conformance Checking · Digital Twin of an Organisation (DTO)

  • This month: Research leading process mining and simulation platforms. Watch introductory webinars and read case studies relevant to our industry.
  • Next quarter: Work with IT to get access to a sample event log from one of our core operational systems. Experiment with a free trial of a process mining tool.
  • Month 4-6: Propose a pilot project for process mining on a specific operational bottleneck, outlining potential benefits and data requirements.
  • Month 7-9: Lead the implementation of a process simulation for a planned operational change, demonstrating how it can de-risk decision-making.

Quick win: Download a free trial of a process mining tool and try to model a simple process using publicly available event log data. Get a feel for the interface and capabilities.

11Staying current once you are in

What people here do to keep up
  • Regularly attend industry conferences (e.g., Lean Six Sigma World Conference, OpEx Week) to stay current on best practices and emerging trends.
  • Actively participate in online forums or professional communities for Six Sigma and Operational Excellence practitioners, sharing knowledge and learning from peers.
  • Dedicate time to continuous learning in advanced analytics, data science, and AI applications relevant to Operations (e.g., online courses, specialised workshops).
  • Seek out opportunities to mentor junior colleagues, as teaching is one of the best ways to solidify your own understanding and leadership skills.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a big chunk of your Black Belt time is spent on repetitive tasks: data cleaning, initial analysis, drafting reports. Imagine if you could cut that down significantly, freeing you up for the truly strategic work. That's where AI comes in.

We're building an AI Productivity Hub specifically for Operations, and for Lead Black Belts like you, it's a game-changer. You'll get access to tools that don't replace your expertise but augment it, helping you accelerate your DMAIC projects and deliver even bigger impacts.

Automated Root Cause Analysis

Use machine learning models to analyse millions of data points from sensors, ERPs, and quality systems. This helps you identify subtle patterns and correlations that predict defects or inefficiencies, going far beyond what traditional statistical analysis alone can uncover. Think of it as having a super-powered detective for your 'Analyze' phase.

Intelligent Process Mining

Gone are the days of endless workshops just to map a process. Leverage AI-powered process mining tools (like Celonis or UiPath Process Mining) to automatically create dynamic, data-driven process maps from system event logs. This instantly highlights bottlenecks, deviations, and rework loops, giving you a real-time, objective view of how things actually flow.

Accelerated Best Practice Research

When you're in the 'Improve' phase, don't start from scratch. Use a generative AI assistant to rapidly search and synthesise technical papers, industry case studies, and our internal project archives. This helps you find proven solutions for similar process problems, kickstarting your solution brainstorming and saving you hours of literature review.

Draft Project & Control Documentation

Let AI handle the initial heavy lifting for your paperwork. Use it to generate first drafts of project charters, stakeholder communications, A3 reports, and even Standard Operating Procedures (SOPs) for your control plans. You'll provide the data and key points, and the AI will structure and draft the content, leaving you to refine and add your expert touch.
