The single most expensive mistake in any restructure is removing the wrong capability. Org-chart-led restructures look at boxes; skills-led restructures look at what each box can actually do. A £199 skills matrix run before the restructure consultation pays for itself the first time it prevents one wrong redundancy or one unnecessary external hire. This brief tells you exactly how to use it.

Why this matters more in 2026 than ever
Reorganisations have always been hard. Done badly, they remove the wrong people, demoralise the right ones, and force the organisation to rebuy a capability it just made redundant. Done well, they reset for the next phase of growth.
What's different in 2026 is the volatility of the underlying skill base. AI has reshaped what individual roles do in less than 18 months. The job descriptions you wrote in 2023 do not describe the jobs in 2026. If you restructure against the 2023 org chart and 2023 JDs, you will almost certainly make the wrong calls.
The cost of one wrong restructure call
Conservative numbers from CIPD and SHRM benchmarks suggest the fully-loaded cost of one wrong redundancy in a knowledge-work role is between £40,000 and £120,000, made up of:
- Statutory redundancy and notice payments (often the smallest line).
- Lost institutional knowledge and customer relationships.
- Recovery hiring (recruiter fees, onboarding, time-to-productivity).
- Damage to remaining team morale (typically 6-12 months of reduced output).
- Possible employment tribunal exposure where process was thin.
If a £199 matrix prevents one such error, it has paid for itself 200x over. Most restructures contain multiple such errors.
How to use a matrix before a restructure
Here is the practical method we recommend to HR Directors and Operations leaders.
Step 1: Build the "target operating model" skill list. Before you touch the org chart, list the 20-30 skills the next-phase business actually needs. Not the skills it used to need. Not the skills the JDs describe today. The skills it will need 12 months from now.
Step 2: Rate every individual against that list, 0 to 5. Use the canonical 0-5 methodology. Be honest. Have the conversations. This is the bit that takes a week, not a day, but it is the bit that protects everything that follows.
Step 3: Overlay the heat map on the proposed org chart. Where are the genuine gaps? Where is the redundant capability? Where are the single points of failure that the proposed structure would amplify?
Step 4: Adjust the proposal before consultation. Almost every restructure we have seen this exercise applied to has changed in non-trivial ways. People who were down to leave were kept; people who looked safe were moved. The proposal that goes to consultation is materially better.
Three patterns we see often
Pattern 1: The disguised single-point-of-failure
One person in the team holds a critical regulatory or customer skill that nobody else has. They look junior on the org chart, so the restructure removes them. Six months later you are paying a contractor £1,500/day to replace what you just made redundant.
Pattern 2: The redundant senior
A senior person whose skill profile, when honestly mapped, overlaps almost entirely with two more junior team members, and who has not added a new skill in three years. The org chart says "keep the senior, lose the juniors." The skills matrix says the opposite.
Pattern 3: The hidden high-potential
A quiet, unflashy team member whose actual ratings put them in the top three for capability and the top one for adaptability. The org chart treats them as background. The matrix surfaces them, and you build the new structure around them, not the loud ones.
Why this is your best legal defence too
In any redundancy or restructure dispute, the question that wins or loses cases is: how did you decide who to keep and who to remove? "We looked at the org chart and made judgement calls" loses cases. "We used a documented capability framework, applied consistently, with manager-and-employee dual sign-off" wins them.
A skills matrix is the cheapest documented, consistent, defensible decision tool you can produce. Many UK employment lawyers explicitly recommend running one before any major restructure for exactly this reason.
The 5-line summary
- Restructures based on the org chart alone make expensive mistakes.
- The cost of one wrong redundancy is £40k–£120k fully loaded.
- A £199 matrix surfaces hidden capability, redundancy, and single points of failure before consultation.
- It is also the strongest documented, consistent decision basis for legal defence.
- Run it before any restructure conversation, not after.
How to start this week
If a restructure is genuinely on the table inside the next 90 days, the realistic path is:
- Day 1: buy the £199 Excel template.
- Days 2-3: with HR, build the 20-30 skill target list for the next-phase business.
- Days 4-10: run the rating conversations across the affected teams.
- Days 11-14: overlay the heat map on the proposed structure. Adjust.
- Day 15: take the adjusted proposal into consultation, with documented evidence.
Two weeks of work, £199 of cost, materially better outcomes for the business and the people in it.
