Most new manager training looks the same. A two or three-day classroom course. A workbook. Maybe an e-learning module. The manager goes back to their desk, opens 47 unread emails, and within a fortnight has forgotten the bulk of what they learned.
In 2026, WSP — a global engineering consultancy with 7,000 employees — took a different approach. Instead of running their people managers through another training programme, they gave them continuous coaching. Seven weeks later, they measured a 24% improvement in manager effectiveness, a 31% lift in employee engagement, and an 8x return on investment.
This post is about why the classroom model keeps failing new managers, what WSP did instead, and how to make the case at your own company.
The unspoken problem with new manager training
Walk into any HR director's office in May 2026 and ask what their biggest L&D headache is. Most will say managers — specifically, the gap between people getting promoted and people knowing how to actually manage. It's the most common reason talented individual contributors leave. It's the most common reason teams underperform.
The instinctive response is to run a training programme. Two days off-site. A reputable provider. A workbook with frameworks. Everyone gets a certificate at the end.
Then nothing changes.
The reason isn't the content. The frameworks taught in good manager training are genuinely useful. The reason is the format.
Behaviour change doesn't happen in a classroom. It happens in a Tuesday morning conversation with a direct report who's pushing back on a decision.
Classroom training assumes that if you give someone the knowledge, they'll apply it. Decades of L&D research says the opposite. The Ebbinghaus forgetting curve — the well-known finding that people forget about 70% of new information within a week without reinforcement — applies to managers as much as to anyone else. Worse, the situations new managers actually face are never the textbook examples. The book says "have a difficult conversation." The reality is a specific person, a specific history, a specific moment of pressure.
A workshop teaches the theory. The application is left to the manager's intuition, which is exactly what they didn't have when they got promoted.
Why most programmes optimise for the wrong outcomes
The other quiet problem with traditional new manager training is what gets measured.
Most programmes measure:
Completion rates
Satisfaction scores at the end of the workshop
Multiple-choice knowledge tests
Almost none measure:
Whether the manager's team is actually performing differently three months later
Whether direct reports rate the manager as more effective
Whether the manager's retention numbers, productivity, or engagement scores moved
This is the gap that gets HR teams fired. Six months after the programme launches, the CFO asks the obvious question: "what did we get for our money?" The answer is usually a satisfaction chart and a hopeful narrative.
What WSP did instead
WSP's challenge in 2026 was the same one most companies face: people managers expected to lead through change, deliver client work, and develop their teams — all without the structured support that executive leaders receive.
Traditional coaching at WSP's scale would have been impossible. External executive coaches charge $300–$500 an hour. A standard six-session package runs $3,000–$5,000 per person. Coaching all of WSP's managers the traditional way would have cost millions before anyone outside headquarters benefited.
WSP deployed Bloom instead. Managers got access to ICF-accredited human coaches through an app, supported by AI-driven daily exercises, psychometric assessments, and continuous tracking. Sessions weren't reserved for a quarterly cadence — coaching became a continuous part of work, with personalised actions sent after every session that managers could mark as completed.
The results, measured in seven weeks:
+31% engagement among coached employees
+30% team communication improvement
+24% manager effectiveness increase
+26% time management improvement
75% monthly active users sustained over time
8x return on investment calculated against programme cost
Emily Binning, a Director at WSP, described what it changed for her:
"In just a short time, coaching has helped me gain clarity, take action, and feel more confident. It's personal, practical, and already making a real difference."
What's actually different about continuous coaching
The frameworks aren't the differentiator. Coaching frameworks have existed for decades. What's different is the operating model.
Three things in particular:
1. Coaching happens in the context of the real situation. A WSP manager preparing for a difficult conversation with a direct report on Tuesday gets coaching from someone who's been trained to navigate that exact type of moment — not someone reciting a script from a workshop they ran three months ago.
2. The system holds the manager accountable between sessions. Bloom's coaches send three specific actions to each manager after every session. The manager marks them as done in the app. The data flows through to Kirkpatrick Level 4 measurement — the level that actually ties learning to business outcomes, rather than to satisfaction or knowledge tests.
3. AI sits behind the coach, not in front of it. When a manager has a question at 9pm before a tough Wednesday morning meeting, they get an AI coach that knows their goals, their psychometric profile, and their company's mission — not a generic ChatGPT response. The AI doesn't replace the human coach. It extends the coach's reach into the moments between sessions, which is where most behaviour change actually happens.
The maths that makes continuous coaching work at scale
The reason executive coaching has historically been reserved for the top 5% of an organisation is cost. At $5,000 per person for six sessions, coaching 500 managers would cost $2.5 million. Most L&D budgets break before they get there.
Continuous coaching priced per employee per month works differently. Bloom is sold on a PEPM basis — a predictable monthly per-employee cost, annual contracts, monthly one-to-one sessions plus continuous AI-supported activity between sessions.
The structural shift is what matters. The per-head cost drops substantially compared with traditional executive coaching, and the volume of coaching per person rises dramatically. The result is roughly ten times more coaching touchpoints per person at a fraction of the traditional per-head price — which is why PEPM is now the operating model for coaching the wider workforce, not just the C-suite.
Approach | Per-head cost | Sessions per year | Continuous accountability |
|---|---|---|---|
Traditional executive coaching | $5,000–$10,000 per engagement | 6 | No |
Group coaching cohorts | $1,500–$3,000 per person | 8–12 group | Some |
Continuous coaching (PEPM platform) | Substantially lower per head — quoted by volume | 12 one-to-one + daily AI support | Yes |
How to build the business case
The classroom-versus-coaching argument is easy to win philosophically. What HR leaders actually need is the business case in a format their CFO will sign off.
Three numbers, on one page.
Cost per head comparison. Your current spend on new manager training (whatever it is), versus continuous coaching. For most organisations, a PEPM platform is cheaper per head while delivering more touchpoints. Lead with the difference.
Retention impact. Bloom customers see an average 12% improvement in employee retention. If your annual voluntary attrition is 15% and the average replacement cost is £50,000 per leaver, a 12% retention improvement across 500 people saves roughly £450,000 a year. Even conservative estimates (5% improvement) pay for the programme.
Payback period. WSP measured 8x ROI in seven weeks. This is the killer number. Most coaching providers tell you to expect twelve to eighteen months before you can show ROI. A programme that pays for itself in one quarter is easier to defend in any budget conversation than one that promises returns "within a year."
Present all three in a one-page memo. Attach the WSP case study. Your CFO will read a page. They won't read a deck.
When traditional training still has a place
In fairness: there are situations where a structured course makes sense. Onboarding the very basics for first-time supervisors. Compliance modules. Specific technical skills (running a payroll review, writing a performance improvement plan). Anywhere the content is genuinely transactional and the goal is knowledge transfer rather than behaviour change.
Where it stops working is everywhere the goal is behaviour change. Leading through ambiguity. Coaching a direct report. Giving feedback that lands. Managing conflict. Building trust with a new team. None of these get learned in a workshop. They get learned in the conversation immediately after the workshop — and that conversation is what continuous coaching makes possible.
FAQ
What is new manager training? New manager training is structured learning for people who have recently been promoted into a people-management role. Traditionally delivered as classroom courses, e-learning modules, or workshops covering topics like feedback, performance management, delegation, and difficult conversations. Increasingly being replaced or augmented by continuous coaching, which delivers ongoing support tied to real situations rather than one-off content.
How much does new manager training cost? Traditional classroom programmes typically run £500–£3,000 per person depending on duration and provider. Executive-grade coaching runs £3,000–£10,000 per person. AI-augmented coaching platforms priced per employee per month are substantially lower per head at enterprise scale, but the specific rate depends on volume and package — most platforms (including Bloom) quote per customer rather than publishing a single number.
Does new manager training actually work? The data is mixed. Most classroom programmes show high completion rates and satisfaction scores but limited evidence of sustained behaviour change. Programmes that combine human coaching with continuous accountability — like Bloom's deployment at WSP — show measurable improvements in manager effectiveness, team communication, and time management within weeks, not months.
What's the difference between training and coaching for new managers? Training transfers knowledge: here's a framework, here's how it works. Coaching helps the manager apply the framework to their specific situation through a guided self-discovery process. Training is broadcast; coaching is individual. The strongest programmes combine both — content modules for the foundations, coaching for application.
How long should new manager training take? A single workshop teaches the theory in 1–3 days. Sustained behaviour change typically requires 90–180 days of continuous reinforcement. Bloom customers typically see measurable shifts in manager effectiveness within 7–12 weeks of starting continuous coaching, with full ROI measurable within a single quarter.
Can AI replace human coaches for new manager development? AI can support a coach but not replace one. A human coach reads context, picks up on subtext, and pushes back in ways an AI currently can't. The most effective model combines both: human coaches set direction during sessions; AI extends accountability and support between sessions. Bloom uses this combined approach in every customer deployment.
What to do next
If you're scoping a new manager programme this year, the question isn't training versus coaching — it's how to build a system that combines both, holds managers accountable between sessions, and measures impact in business terms your CFO recognises.
