Business transformation: what fifteen years of research tell us about the minority that succeeds

Situation, complication, recommendation

Situation. Transformation has become the normal state of business. Bain estimates that more than a third of large organisations are undertaking one at any given time ^[3], and McKinsey now describes transformation as a permanent condition rather than a one-off programme ^[5].

Complication. Success rates have barely improved in fifteen years of measurement, and value starts to be lost when objectives are set, even before operational delivery begins ^[1].

Recommendation. Treat transformation as a management discipline — an ambitious, quantified target, dedicated talent and weekly tracking of value — rather than a succession of initiatives.

1. Low success rates that depend on the definition used

The figure of “70 % failure” has circulated since the 1990s. A review by Mark Hughes published in 2011 in the Journal of Change Management found no valid empirical basis for this universal rate ^[6]. Recent studies are more useful, provided their definition of success is read carefully.

The higher the standard — achieving the original ambition rather than simply “improving” — the lower the rate. The practical lesson: define from day one what “success” means, in EBITDA, cash and timing.

2. Value is lost from day one

McKinsey’s global survey “Losing from day one” (Michael Bucy, Bill Schaninger, Kate VanAkin and Brooke Weddle, December 2021) breaks down value lost over the course of a transformation ^[1]: around 22 % is lost when setting objectives, 23 % during planning, 35 % during implementation and 20 % afterwards. Almost half of the loss therefore occurs before operational delivery begins.

Two other findings stand out. Respondents from successful transformations estimate that they captured 67 % of the maximum possible benefit, compared with 37 % for the others ^[1]. And across fifteen transformations studied in detail, companies delivered on average 2.7 times more value than their leaders had initially thought possible ^[1]: insufficient ambition is a hidden cost.

3. Three levers on which the studies converge

A quantified ambition, translated for everyone

In its report “Flipping the Odds of Digital Transformation Success” (2020), BCG ranks an integrated strategy with clear, quantified transformation objectives as the leading success factor ^[2]. McKinsey observes that companies setting targets equivalent to at least 75 % of their earnings over the previous twelve months are more likely to achieve total shareholder returns (TSR) above those of their peers ^[1], and that successful transformations make those objectives tangible for every employee, notably through face-to-face communication.

The best talent in critical roles — without exhausting them

According to Bain & Company’s Transformation & Change survey (2024), fewer than 5 % of roles generate around 90 % of a transformation’s value ^[3]. 56 % of companies that transform successfully avoid overloading their key executives, compared with 44 % of the others; two-thirds of them allocate at least half the time of those assigned to their new role. In Bain’s database of more than 24 000 initiatives, having a dedicated chief transformation officer is associated with 24 % more planned value ^[3].

Rigorous execution

McKinsey’s most recent research, “Rigor: What it takes to turn ambition into impact” (David Ebenstein, Dominic Skerritt, Rajesh Krishnan and Zachary Silverman, April 2026), covers 72 transformations ^[4]. “Rigorous” organisations — those achieving more than 80 % of their target within 24 months — stand out clearly:

These organisations add new initiatives throughout the programme, track value every week and define clear thresholds for intervention ^[4]. Above all, the levers work only together: at BCG, companies that properly addressed only three or four of the six identified factors failed, while those addressing all of them increased their chances of success from 30 % to 80 % ^[2].

4. In 2026, transformation becomes permanent — and organisational

The 2026 edition of McKinsey’s The State of Organizations report (Alexis Krivkovich, Damian Klingler, Dana Maor and Patrick Guggenberger), based on more than 10 000 executives, calls for a “dual transformation”, both technological and organisational: 88 % of organisations are experimenting with AI, but 81 % report no significant gains in their results ^[5]. On reorganisations, Bain noted in January 2026 that 88 % of executives believe their new structure will achieve its objectives, compared with 36 % of the employees working within it, and that only 22 % of employees feel they have received sufficient support ^[7]. The gap between the organisation chart and how work actually gets done remains the largest source of lost value.

5. Our takeaways

Before launching — or relaunching — a transformation, five questions for an executive or shareholder:

1. Is our target quantified in EBITDA and cash, time-bound and ambitious enough?
2. Have we identified the handful of roles that will deliver most of the value, and placed our best people in them with the time they need?
3. Who leads the transformation full-time, and with what mandate?
4. Do we track value weekly, initiative by initiative, with clear thresholds for intervention?
5. How will we embed the gains in day-to-day operations once the programme ends?

This is the logic behind our approach: diagnosis, a value creation plan, execution alongside management and measurement of results.

Limitations. These studies rely largely on executives’ statements and consulting firms’ databases; they establish correlations, not causation. Their figures should be read as converging orders of magnitude.
