Strategy Execution: Turning a Three-Year Plan into a 90-Day Cadence

Most strategies are not wrong; they are under-delivered. Harvard Business Review reported in 2005 that companies typically realise only about 60% of their strategies' potential value because of defects and breakdowns in planning and execution. Bain's Michael Mankins, writing in the same journal more than a decade later, reported that executives say they lose 40% of their strategy's potential value to breakdowns in execution. Two eras, two authors, one consistent gap. The plan is rarely the binding constraint. What constrains results is what happens between the board paper and the Monday-morning diary.

The mechanism is visible at middle-management level. Donald Sull's research, published in Harvard Business Review in 2015, concluded that two-thirds to three-quarters of large organisations struggle with execution, and that only half of middle managers can name any of their company's top five priorities. If the people who allocate time, hire and approve spend cannot name the priorities, the strategy is not guiding decisions; it is decorating them. Each unaligned decision is small. Across a year, thousands of them move the organisation somewhere the leadership team did not choose.

For a UK chief executive, the implication is uncomfortable but practical. The execution gap is not a failure of intelligence or effort; it is a design problem in the handover. Strategy is written by a small group, then passed to people who were not in the room, who already have full diaries and an unchanged budget. Unless the handover converts intent into named owners, dated outcomes and funded resources, the default is business as usual with new vocabulary. That default is entirely rational for the people living it.

Start with a diagnostic, not a new framework. Ask ten managers below the executive team, separately, to write down the company's top three priorities and what they will do differently this quarter because of them. Compare their answers with your own. The spread is your execution gap in a form the leadership team cannot argue with. It costs an afternoon, and it tells you whether the problem is clarity, capacity or commitment, which need different remedies.

There is also a UK-specific reason to act. Many British mid-market companies are led by a small executive team that shares one diary and, often, one adviser. In that setting the handover is a handful of conversations rather than an organisation-wide cascade, which makes it easier to repair than in a large corporate. The same smallness means a single unowned priority is visible within weeks. Small teams have few places to hide, and that is an advantage if they choose to use it.

McKinsey's survey of 617 executives and managers, published in 2024, asked how strategy reaches the budget. Only about half said their companies effectively align their budgets with strategic goals, and just 53% said their organisations are in the habit of fully funding the priorities they have identified. A strategy that is only partly funded is a wish list with a deadline. The unfunded priorities compete for people and attention with the existing business, and the existing business, which has revenue, customers and a track record, usually wins.

The same survey points to a second weakness. Just 28% said their organisations almost always rank their top ten to 30 most important programmes against each other, and just 28% said top management encourages high-potential, risky projects. Without ranking, everything remains a priority; without appetite for risk, the portfolio drifts towards the safe and incremental. Earlier McKinsey research, drawing on executives in more than 500 distinct companies, found that companies that actively reallocate resources tend to excel in three main areas, and that some business units used a rolling 18-month performance forecast to make reallocation routine.

For a CEO, the lesson is that the budget cycle is where strategy is either decided or quietly abandoned. If the annual budget is built from last year's numbers with a growth uplift, the strategy has not reached the money. The finance director then becomes the unintended strategist, because their allocations are the only decisions with force. That is no criticism of finance; it is the consequence of leaving strategy outside the process that moves cash and headcount. The remedy is to bring the two into one conversation, on one calendar.

In practice, take the quarterly commitments, cost each one, and fund them first. Everything else is funded from what remains. Then agree in advance which commitments may draw on resources freed if another is stopped. In a smaller company the exercise fits on one page: commitments down the side, people, cash and management time across the top. If the page does not balance, the plan is too big, and it is better to learn that in the first week than in the third month.

One further test is whether a priority survives a bad month. When revenue dips, discretionary spend is cut, and the first casualties are usually the investments the strategy depends on: the hire, the pilot, the market study. Ring-fencing a small number of commitments in advance, and naming who may release that money, prevents the strategy being funded only in good months. It also gives the finance director a clear rule, so that protection is a decision taken calmly rather than a debate held under pressure.

A three-year strategy answers the question of where the company is heading. It does not say what each executive will have finished by the end of next quarter. Ninety days is the shortest period in which a meaningful commitment can be completed, such as a pricing change, a key hire, a partner agreement or a system migration, and the longest over which a leadership team can hold a priority in mind without drift. Annual goals are too distant to create urgency, and monthly goals reward activity over outcomes. The quarter is the natural unit for a commitment someone can own.

In the UK the conditions for installing routine are improving. The Office for National Statistics reported that the mean management practices score for UK firms rose from 0.51 in 2020 to 0.57 in 2023 on a scale from zero to one, and that the median rose from 0.53 to 0.61. The index covers practices such as targets and monitoring. Yet the Chartered Management Institute reports that as many as 82% of new managers in the UK are accidental managers. People who arrive in the role without preparation will follow a simple routine more reliably than a sophisticated framework.

The implication is to design for the manager you have, not the one in the textbook. A ninety-day commitment that fits on one page, is owned by one named person and is reviewed in the same room each month will be used. A twelve-page objectives document with cascading key results will be admired and ignored. Whether you call the unit an objective, a rock or a commitment matters less than three properties: it is finite, it is measurable and the owner helped to choose it.

Limit the load. Each strategic priority should translate into no more than three commitments per quarter, and the leadership team as a whole should carry no more than about a dozen. Beyond that you have a list, not a set of choices. If the first draft has thirty items, the team has not yet decided what matters. Send it back and ask what would happen to the business if only five were completed. The answer usually clarifies which five.

A short note on OKRs. Objectives and key results are a sound format for writing commitments, and many leadership teams find them useful, provided the key results are few, measurable and owned. The common failure is to adopt the format without the cadence, so that the quarter ends with scores nobody discusses. Whatever the label, the test is the same: does a named person stand up each month and say what has moved, what is blocked and what they need? If not, the format is not the problem.

Cadence is what keeps a commitment alive after the launch meeting. We would install four layers. A weekly leadership check-in clears blockers and takes no more than forty-five minutes. A monthly operating review inspects progress against each commitment and the leading indicators behind it. A quarterly reset closes the quarter, retires or renews commitments and resets the budget. An annual strategy refresh tests the three-year direction against evidence. Each layer has a fixed agenda, owner and place in the calendar, so nobody has to decide whether to hold it.

Consistency matters more than sophistication. Meetings should use one page per commitment, with a status the owner declares before the meeting rather than negotiates in it. Red status should be treated as information, not failure; a team that never reports red is either not stretching or not being candid. The chair asks the same three questions each time: what has moved, what is blocked, and what do you need from this room. Over a few quarters the pattern of answers becomes the most reliable management information the company has.

A cadence also protects the CEO's time. Without a rhythm, the chief executive becomes the integration layer, chasing updates and settling disputes in corridors. With one, the meeting structure does the integration, and the CEO's attention goes to the few decisions only the chief executive can take. This is especially valuable in owner-managed and mid-market businesses, where the leadership team is small, each executive runs a function and the chief executive is also the principal salesperson, lender contact and culture-setter.

Put the whole year's meetings in diaries now, and protect them as you would a lender meeting. Publish the agenda template. Ask each executive to bring a one-page status to the first monthly review, even if it is rough. The first two reviews will be untidy; by the third, the team will prepare differently, because they know what will be asked. If a meeting is cancelled twice, treat that as a signal that the commitment it covers is not really a priority.

Finally, keep the cadence human. A short, regular, well-run meeting builds trust faster than a long, irregular, ambitious one, because people learn that their time will be respected and their problems heard. In the first quarter, the leadership team will judge the cadence by whether it saves them effort. If the weekly check-in removes a blocker that would otherwise have cost a week, the habit will hold. If it only produces reports, it will be quietly abandoned by the second quarter.

The governance debate is moving in the same direction. In NACD's 2026 Governance Outlook, 60% of directors ranked the board's oversight of strategy execution as the top oversight improvement area, 62% said they are increasing strategy discussions in board meetings, and 44% are spending more time with the C-suite and senior management. The respondents are US directors, but the direction of travel applies to UK boards and investors as well: directors increasingly want evidence of delivery, not only approval of plans.

Directors ask for evidence because the cost of weak delivery is visible to shareholders and lenders, including in private companies. A board that sees only the annual plan and the monthly accounts cannot tell whether the strategy is working until the numbers move. A board that sees ninety-day commitments, owners and leading indicators can ask better questions earlier, and can distinguish a miss caused by poor execution from a miss caused by a wrong assumption. That distinction is the difference between replacing a manager and revising a plan.

For the CEO, the commitments are also a governance instrument. They give a precise answer to the question every non-executive eventually asks: how will we know the strategy is working before the results say so? They also protect the executive team from unstructured intervention, because a board that can see delivery has less reason to second-guess. Reporting should be short. Five to seven company-level commitments, each with a status, an owner and one leading indicator, is enough for a board pack.

Ask your chair what they would want to see each quarter and agree the format before the first reset. Share the full commitment set, including those you have decided to stop and why. A kill decision explained in writing is one of the strongest signals of management credibility a board can receive. Boards that see only successes tend to assume the stretch is too low; boards that see disciplined stops tend to trust the numbers that remain.

Most organisations are good at starting and poor at stopping. McKinsey's survey found that just 28% of respondents say top management encourages high-potential, risky projects, which suggests that for most leadership teams the cost of a visible failure outweighs the benefit of a bold attempt. The result is a portfolio of safe, slow-moving commitments that never quite end. Kill criteria change the calculation. If the team agrees in advance what evidence would cause a commitment to stop, stopping becomes the application of a rule, not an admission of defeat.

A kill criterion should be specific and observable. For a new product line: fewer than an agreed number of qualified pilots by an agreed date. For a partnership: no signed agreement by the end of the second month. For a hire: the role still unfilled after two rounds of search. The number matters less than when it is set. It should be set when the owner is optimistic and the team is calm, not in the quarter when sunk cost makes everyone defensive. Write it on the commitment card and read it aloud at every monthly review.

Kill criteria also free capacity. Every commitment that stops releases people, cash and attention for one that is working, which is the active reallocation McKinsey associates with stronger performance. It changes culture too. When the chief executive thanks an owner for stopping something early, the organisation learns that candour is valued above persistence. That is the culture in which people bring bad news at week four, when it is cheap, not at week twelve, when it is expensive.

Add three fields to every commitment card: the owner's name, the review date and the kill criterion. Reject any commitment that arrives without all three. Allow owners to propose a revised criterion once, in writing, at a monthly review, not repeatedly. Give the team a simple record for stopped work: what was tried, what was learned and what was released. Over a year that record becomes a useful library of decisions, and a quiet reference for the next strategy refresh.

Honest stopping also improves the quality of starting. When owners know a commitment can be ended without blame, they propose more ambitious ones and define success more precisely, because they have less reason to hedge. Teams that cannot stop tend to promise less and quietly widen the definition of done. Over several quarters the contrast is visible in the commitment cards themselves: precise, bold and time-bound in one company; vague, cautious and open-ended in the other.

Do not launch a programme. Launch one quarter. In week one, the leadership team lists the strategic priorities and agrees no more than three commitments for each, written on commitment cards. In week two, owners present their cards to the group, and the team challenges, merges and removes. In week three, the finance lead costs the set and the team funds it. By the end of the first month, the first monthly review is in the diary and the board has seen the set. The pace is deliberately brisk, because momentum is part of the method.

For groups operating in more than one market, such as the UK and the Gulf, the same cadence should run across all of them, with regional owners named on the cards. Calendars, public holidays and decision styles differ, and review times should respect them, but the structure should not change. A single commitment format is what lets the chief executive compare a European partnership with a Saudi or UAE market-entry step on equal terms, and decide where the next pound of management time should go.

The first quarter will not be perfect. The aim is to establish the habit and expose the weak points: unclear priorities, unfunded commitments, owners with too much to do. Expect to find that two or three leaders are overloaded and that at least one priority has no real owner. That finding is the value. It is the information the strategy document could never give you, because it was written before the team had to live with it.

At the end of the quarter, hold the reset. Score each commitment as delivered, partly delivered or stopped. Reset the budget. Then write the next set. By the third reset the team will be ahead of the document: the three-year strategy will have been tested against real quarters, and the commitments will be the main way the company talks about its direction. That is what it means for strategy to be owned by the people who deliver it.

Karter McKinley's Strategy & Transformation work focuses on the handover from plan to operations. We help leadership teams translate a multi-year strategy into funded ninety-day commitments, set the review rhythm and write kill criteria, and we support the first quarterly resets alongside management. The aim is a cadence the team runs itself.
