Step 1: Start with data, not assumptions
Every system has its limits. The real question is: do you know where yours are?
Too often, organisations start their development efforts based on vague or ill-defined beliefs about “culture”, “engagement” or “purpose”. But what if you could measure performance limits precisely and target development where it matters most?
That’s why we always start with developmental diagnostics. Here are 3 of our favourites:
The Complete Energy Audit
Reveals physiological capacity and burnout risk across the system using Heart Rate Variability. One client saw a 21% uplift in capacity within 6 months by targeting recovery patterns.
The Complete Behaviour360
Uncovers behavioural blind spots in your leadership team. Our work with Tesco helped unlock 10 years of leadership development in just 12 months by using the Behaviour360 to pinpoint where leaders were stuck.
The Complete Values Profile
Maps the true values of the organisation and lets you see how aligned the system is. This allows you to identify whether your culture is ready to evolve, where to evolve from and how to bring others with you.

Step 2: Sequence your development by quarter
You can’t develop everything all at once. It’s why we often start with a developmental diagnostic first so you can identify where to have the biggest impact. So, here’s how we recommend sequencing the work over four quarters.
Q1 – Discover the Current System
- Run diagnostics (Energy Audit, Behaviour360, Values Profile) for key leaders or teams within your organisation.
- Map your leadership capability, team maturity, and system constraints.
- Using the insights gained from the developmental diagnostics create a cross-functional picture of what’s really going on.
- Begin supporting key individuals based on their development plan who will have key influence in the system or to boost them quickly.
Q2 – Decide What Must Shift
- Build a development strategy that connects the insight to into action
- Prioritise key teams, leaders, and functions
- Establish quarterly developmental sprints, anchored in data.
- Launch high-impact programmes (e.g., Team Journey, Coaching, Complete Academy)

Q3 – Develop Capability + Coherence
- Embed new leadership behaviours (through coaching and academies)
- Shift team dynamics with facilitated Team Journeys.
- Strengthen governance, accountability, feedback, and decision-making rhythms.
- Re-assess to understand impact on physiology (e.g., HRV) to support energy and emotional regulation.
Q4 – Deliver at a New Level
- Codify changes into rituals, routines, and roles.
- Use values and physiology to sustain change, not rely on willpower
- Build internal capability to self-sustain developmental work
- Re-assess progress with the same diagnostics you started with
Step 3: Define what success really looks like
At Complete, we help clients define success across the areas that matter most to them. That might mean looking at:
Commercial Impact
Ultimately performance still matters. We look at how leadership development translates into improved productivity, reduced waste, and ultimately, stronger profitability.
Our work with Phrase helped them build internal capability to deliver faster, scale sustainably, and win industry awards. All within 12 months.
Decision Quality & Speed
When leaders develop, they start making better decisions, faster. The result? Fewer bottlenecks, clearer priorities, and a shift from reactive firefighting to proactive execution. That’s how Tesco compressed 10 years of team development into one, unlocking clarity and momentum across the system.
Talent Retention & Culture
Regretted attrition is a hidden cost in most organisations. But when leadership improves, so does the employee experience.
Development becomes a reason people stay. You retain top talent, build trust, and unlock discretionary effort.
Ultimately, success is about more than just outcomes.
It’s about building a system that evolves, without relying on heroic effort.
Ready to future-proof your organisation?
The path isn’t easy. But it can be measurable. And with the right diagnostics, development, and discipline, you can build an organisation that not only survives uncertainty, but thrives because of it.
Start with your system’s data. Act on what’s real and build capability that compounds.
