The story earns its retention headline with two concrete numbers: a 43% drop in developer turnover and £486,000 in avoided recruitment cost, which gives readers something to benchmark against. The before-state is credible because the HR leads explain exactly what disruption caused the uncertainty, not just a vague pain point. The mechanism is thin but present: exit interviews combined with engagement surveys surfaced actionable themes that drove targeted programs rather than expensive misdirected spending.
The ROI is anchored to a fully loaded cost-per-hire figure (£6,000 per position), which converts a soft people metric into a CFO-legible business case without overclaiming.
