Steve McNicholas delivering a leadership session
The Accelerator 100 Programme

Theory is cheap. Implementation is everything.

The Accelerator 100 is deliberately not your typical leadership event. Two days to understand the framework — then 100 days where I stay with your leaders, holding every one of them accountable for real change.

The real problem

Most organisations run "DIY leadership".

Every leader runs leadership their own way, across every layer — unmonitored, unscaled, and compounding. There's no shared playbook, so success depends on personalities rather than an engineered standard. Monitoring and scaling fifty-five variations of leadership is exhausting and near impossible. Scaling one operating system is where growth and ambition are achieved.

The framework

One operating system, built on three foundations.

High performance isn't created by charisma or workshops. It's created when leaders at every level can self-lead, team-lead and performance-lead with clarity and consistency.

The Leadership SUCCESS Engineering framework wheel — three foundations and seven enablers
Foundation 1

Self-Leadership

Accountable, self-aware and disciplined. The leader owns their development and their results.

Foundation 2

Team-Leadership

Aligned, united and enabled. Every individual pulling toward one common purpose and outcome.

Foundation 3

Performance-Leadership

Candid, courageous and results-focused. Turning intent into measurable, predictable delivery.

S.U.C.C.E.S.S.

The seven key enablers.

Just a handful of leadership qualities — but on the Pareto principle, they tackle the majority of challenges leaders face every day. Each enabler creates a leadership persona.

S
The Foundation

Self-Awareness & Accountability

Being wholly accountable for your own development and the outcomes of you and your teams.

U
The Anchor

Unity of Purpose & Outcomes

Aligning and uniting the team to a common purpose — capturing the win-win for every stakeholder.

C
The Bridge

Candour & Clarity of Expectation

Operating with high candour and total transparency, giving everyone the clarity they need to perform.

C
The Catalyst

Courage & Change Execution

The courage to name an issue and change it with conviction — and the discipline to persist through headwinds.

E
The Multiplier

Enablement & Empowerment

Ensuring every person has the tools, skills and support to perform — and empowering them to achieve more.

S
The Futurist

Scorecard & Solutions Mindset

Reading the patterns in your metrics and defaulting to solutions, not excuses — acting early.

S
The Legacy

Stewardship & Tomorrow Thinking

Being a steward of your team's feelings and challenges — kind leadership, not merely nice leadership.

The Result

One Leadership Operating System

Three foundations and seven enablers combine into a single, scalable system — your Leadership OS™.

How it works

2 days of theory. 100 days of accountability.

An in-person two-day workshop (9am–6pm), then three structured check-ins at roughly 30, 60 and 100 days. Ideal cohorts of 6–10, so every delegate works closely with me throughout.

Pre-work
Day 0
Diagnose

Baseline diagnostic & intro call

Every delegate completes the Leadership SUCCESS Engineering™ assessment to establish a personal baseline. We address questions up front, so day one starts with momentum.

Workshop
Day 1
Theory

Understand the framework

A classroom session of open, honest self-reflection across the seven core themes — exploring the models, insights and frameworks that bring real clarity.

Workshop
Day 2
Plan

Build your Leadership Effectiveness Plan

Delegates reach an effective baseline across all seven themes and draft a personal plan, prioritising where progress, action and focus is needed most.

Check-In 1
~30
Implement

Reset accountability

The first checkpoint at 1:1 and cohort level. Short cycles of application, feedback and adjustment — focused on real work, not classroom simulations.

Check-In 2
~60
Enhance

Sharpen execution

The mid-point checkpoint. We enhance delivery of each plan, remove barriers, and turn early progress into embedded leadership habits.

Check-In 3
~100
Conclude & Sign-off

Evidence the change & ROI

The final checkpoint concludes plan delivery, provides executive MI and a summarised ROI, and confirms individual effectiveness to the sponsoring executive.

This 100-day phase is where the growth, change and ROI are created.

Delegate feedback

From the leaders who did the 100 days.

Thoroughly enjoyed the 100 days. Totally different to expectations! Steve breaks leadership down to seven core blocks. The follow-up is intense but it makes the difference.
Michael
Head of Sales
As a newbie leader, I had no idea it would be so beneficial. Steve has given me the best possible start in my leadership career and I'm ever so grateful.
Amanda
Project Director
I'm already seeing huge change thanks to the strategies Steve shared, as are my teams. Steve is undeniably an inspirational leadership coach.
Ian
Data Manager
This was the best event I've ever attended. His relentless intensity in the follow-up period forces you to commit to the actions — and the results are so worth it.
Steve
Purchasing Manager
I admit I was a little doubtful, but I'm so glad I was invited. He questions you, holds you to account and encourages you to thrive — and he makes it simple!
Mick
Head of Quality
A must for anyone who truly wants to be a better leader. He'll take you out of your comfort zone and push you to improve in areas you never even considered.
Susan
IT Director
A programme that finally shares what real, effective leadership is all about. Scary but good when he's pushing — and genuinely supportive in the crucial weeks that follow.
Ryan
Deputy CFO
Refreshing! The first one of these where I had no excuses and no place to hide. Steve sets out the model, helps you understand it, and for the next three months he drives you on.
Paul
Sales Director
