How M.A.S Works works
Map → Automate → Scale
The size of the job changes. The basic approach does not.
Scale does not simply mean getting bigger. It means building a business that can handle what comes next.
The problems M.A.S Works helps solve
Businesses call me for different reasons. An owner may be buried in admin, a transformation director may need an important programme back on track, and a growing company may need more senior operational leadership. In each case, the starting point is the same: understand how the business is working now and what is getting in the way.
M.A.S Works looks at how the business really runs, finds where time or money is being lost, improves the processes and systems behind it, and helps make those improvements stick. That can be a 90-day piece of work or a longer role inside the business.
Typical reasons
I am working 60 hours and too much still comes back through me.
Owner-run SME
The programme needs experienced ownership and there is nobody available to take it on.
Transformation director
The business has grown, but the way we run it has not kept up.

How M.A.S Works can help
Four ways to work with Jez
The right approach depends on the size of the business, the problem you are trying to solve and how much support you need.
- 01
Operational Business Improvement
Owner-managed businesses · West & North Yorkshire
If too much still depends on you, processes are creating unnecessary work or the business is losing time and money through the way it operates, I help you work out what needs improving and get the changes made.
- 02
Exit Ready Strategy
Owner-managed businesses planning to sell, hand over or step back
If you are thinking about selling, succession or stepping back in the next three to five years, the review runs with that in mind: what makes the business transferable, what depends on you, and what to fix first.
- 03
Project Delivery
UK-wide · remote and on-site
If an important project, programme or piece of change needs experienced ownership, I can step in, take responsibility for delivery and get it moving.
- 04
Fractional COO / CTrO
UK-wide · remote and on-site
Senior operational and transformation leadership for scaling businesses that need experienced support at leadership-team level without making a full-time executive hire.
An hour to talk through what is happening and work out whether M.A.S Works is the right fit.
Case study
Building the infrastructure for a plumbing business's next chapter
A Bingley plumbing and heating business with a clear plan for 2028 and no infrastructure to get there. Seven areas of the business reviewed, the processes written down, and the owner freed from the work that only he could do.

The output
The RAG Diagnostic
For owner-run businesses, the RAG Diagnostic gives a simple picture of where your time is going. Red is work to stop or hand over, amber is work someone else can manage with your oversight, and green is work that genuinely needs you.
Most of your time on tasks you shouldn't still be doing.
Red
Stop doing, delegate out
Amber
Delegate, with oversight
Green
Focus here, only you
I fill in your actual split with you during the first conversation. It gives us a starting point and something practical to measure as the work progresses. You keep the completed sheet.

Who is behind M.A.S Works
I'm Jez Bristow.
Before setting up M.A.S Works, I spent more than 12 years at Direct Line Group, progressing from project and delivery roles into senior commercial, product and transformation positions on the Green Flag Executive Team.
My work has covered major partnerships, project and programme delivery, product, digital transformation, data, commercial performance, customer experience and large-scale operational change.
At Green Flag, that included helping transform a 50-year-old business with more than three million customers while it continued operating 24 hours a day, 365 days a year.
I set up M.A.S Works in January 2025 to bring that experience into businesses that need practical help improving how they work or delivering important change.
