7Would you like it

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

What people enjoy
Solving Complex Puzzles

You'll be given the really tricky, ambiguous problems that no one else has managed to crack. This means diving deep into data, talking to dozens of people, and figuring out the true root cause of a messy operational issue.

Being asked to figure out why customer complaints spiked by 30% last quarter, when everyone else thought it was just 'bad luck'.

Driving Tangible Impact

Your work will directly lead to significant cost savings, efficiency gains, or improved customer experiences. You'll see the results of your efforts in the company's financial reports and in the daily lives of your colleagues.

Implementing a new process that cuts our order fulfilment time by half, directly leading to a measurable increase in customer satisfaction scores.

Building Capability in Others

You'll spend a good chunk of your time mentoring and coaching your team and other business unit staff, helping them develop their own problem-solving skills and grow their careers.

Guiding a junior consultant through their first complex DMAIC project, watching them present their findings confidently to a senior leadership team.

What frustrates people
  • Dealing with leaders who pay lip service to 'Lean' but won't commit resources or change their own behaviour.
  • Spending 30-40% of project time on data scavenger hunts across fragmented, legacy systems.
  • Being perceived as the 'process police' rather than a true partner, constantly fighting the bureaucracy stereotype.
  • Stakeholders who come with a pre-defined 'solution' (e.g., 'We need new software!') instead of an actual problem to solve, skipping the analysis phase.
  • Watching a perfectly designed new process slowly revert to the old, inefficient way of working because the change wasn't truly embedded or sustained.
  • The constant battle to quantify the 'soft' benefits (like reduced employee frustration or better decision quality) into hard financial ROI for the Finance team.
What this role does not give you
  • A quiet, predictable routine with minimal stakeholder interaction.
  • The ability to make decisions unilaterally without needing to build consensus.
  • A guarantee that every single project you lead will be implemented exactly as designed.
  • A role where you only focus on the technical aspects of process improvement, without the 'people' side of change.

8Who you work with

This role directly shapes the efficiency and effectiveness of our core business processes. You'll be accountable for delivering significant financial savings and operational improvements across multiple business units, influencing how we operate at a strategic level. Your work ensures that our internal consulting function is seen as a strategic partner, not just a project delivery team.

Inside the business
  • VP of Operations
  • Head of Finance
  • Product Leadership
  • Head of Customer Service
  • IT Programme Managers
  • HR Business Partners
Outside the business
  • External audit partners (for process controls)
  • Key vendors (for supply chain optimisation projects)
  • Industry bodies (for benchmarking and best practice sharing)

9What you need before you start

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

  • Master Black Belt certification (or equivalent demonstrable expertise in advanced Lean Six Sigma methodologies, including Design of Experiments and multivariate analysis).
  • Proven experience leading multiple complex, cross-functional improvement projects with significant, quantifiable financial benefits (typically £1M+ in realised savings).
  • Demonstrable experience managing and mentoring a team of junior process improvement professionals.
  • A strong track record of influencing senior stakeholders (VP level and above) and driving organisational change without direct authority.
  • Expertise in at least one major statistical software package (e.g., Minitab, JMP) and advanced process mapping tools (e.g., Visio, Lucidchart).
  • Excellent presentation and facilitation skills, comfortable leading large workshops and presenting to executive audiences.

10What to practise next

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

Data Science for Process Improvement

The sheer volume and complexity of data available mean that traditional statistical tools alone might not be enough. Integrating data science techniques (like machine learning for predictive analytics or advanced clustering for process segmentation) will allow us to uncover deeper insights and build more robust, intelligent processes.

Predictive Modelling · Clustering & Segmentation · Feature Engineering for Process Data · A/B Testing Design & Interpretation (Advanced) · Introduction to Python/R for Data Analysis

  • This month: Take an online introductory course on Python for data analysis (e.g., DataCamp, Coursera).
  • Next quarter: Identify a project where you could apply a simple machine learning model (e.g., predicting customer churn based on process touchpoints).
  • Next 6 months: Collaborate with a data scientist in our IT team to understand how they approach process-related data problems.
  • Next 9 months: Build a basic predictive model for a process metric using Python or R.
  • Within 12 months: Lead a project that formally integrates a data science component into a Lean Six Sigma initiative.

Quick win: Explore publicly available datasets related to process operations (e.g., manufacturing defects, call centre logs) and try to apply simple statistical analysis in Python or R. Even basic data manipulation will build foundational skills.

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 trends and network with peers.
  • Contribute to internal knowledge sharing sessions, presenting on new methodologies or successful project case studies.
  • Actively participate in online communities or forums dedicated to Lean Six Sigma and process excellence, sharing insights and learning from others.
  • Seek out opportunities to mentor junior colleagues, even informally, to solidify your own understanding and leadership skills.
  • Dedicate time each quarter to self-study on emerging technologies like AI in process mining or advanced data analytics techniques.

12The rising capability

What's rising in its place

This is where the work is heading, and the higher pay with it. Get fluent here and the shift stops being a threat and starts being your edge.

AI-Driven Process Mining & Simulation

Traditional process mapping is slow and often relies on 'what people say happens'. AI-driven process mining tools (like Celonis or UiPath Process Mining) automatically pull data from system logs to show 'what actually happens', highlighting bottlenecks and deviations instantly. This is a game-changer for the 'Measure' and 'Analyse' phases, making them far more accurate and efficient.

  • Event Log Analysis
  • Digital Twin of an Organisation (DTO)
  • Conformance Checking
  • Predictive Process Monitoring
  • AI-powered Root Cause Identification

Advanced Digital Facilitation & Collaboration

Hybrid and remote work isn't going anywhere. We need to be just as effective (if not more so) at running engaging, productive workshops and collaboration sessions online as we are in person. This goes beyond just knowing how to use Teams or Zoom; it's about designing truly interactive digital experiences that drive engagement and results.

  • Virtual Whiteboarding Mastery
  • Hybrid Meeting Design
  • Asynchronous Collaboration Strategies
  • Digital Icebreakers & Engagement Techniques
  • Data Visualisation for Remote Teams

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be honest, a lot of the grunt work in process improvement—data gathering, initial analysis, drafting reports—can be a real time sink. Imagine if you could offload a significant chunk of that to an intelligent assistant. That's exactly what AI can do for a Lead Consultant in Process Excellence.

We're not talking about replacing your critical thinking; we're talking about giving you a powerful co-pilot. By automating the tedious, repetitive tasks, you're freed up to focus on the truly strategic work: deep problem-solving, complex influencing, and building your team's capability. Think of it as having an army of junior analysts at your fingertips, ready to crunch numbers and draft documents in seconds.

Process Mining Autopilot

Use AI-powered process mining tools (like Celonis or UiPath Process Mining) to automatically analyse system event logs from our ERPs (SAP, Oracle) or other core systems. This instantly generates detailed, data-driven 'as-is' process maps, highlighting bottlenecks, deviations, and rework loops that would take weeks of manual interviews and observation. You'll get to the 'Define' and 'Measure' phases of DMAIC much, much faster.

Root Cause Analysis Accelerator

Feed structured problem statements, hypotheses, and large datasets into an AI analytics platform. The AI can perform millions of calculations and correlations in minutes, identifying statistically significant drivers and root causes that a human might miss or take days to uncover. This supercharges your 'Analyse' phase, letting you validate hypotheses and pinpoint issues with unprecedented speed and accuracy.

Benchmarking & Research Assistant

Need to know the average cycle time for accounts payable in the manufacturing sector? Or best practices for call centre first-call resolution? Use an AI assistant to rapidly scan vast amounts of industry reports, academic papers, and case studies. It'll pull out relevant benchmarks, key trends, and potential solutions in minutes, saving you hours of manual research for your 'Improve' phase.

Charter & Comms Co-Pilot

Leverage generative AI to create a first draft of a project charter, a tollgate review presentation, or a complex stakeholder communication email. Input a few key details, and the AI provides a solid, well-structured starting point. You're no longer staring at a blank page; you're refining and adding your strategic insights, saving significant time on major deliverables and communications.
