Stacey Slinger · Cape Town, South Africa

Read the system. Shift the pattern. Move with intent.

I'm a researcher and practitioner of systems leadership. I write, research, and consult — helping South African organisations get underneath the symptoms and address what's actually driving attrition, disengagement, and leadership gaps. This work sits under a practice called Culture by Design.

Stacey Slinger · Cape Town

Researcher. Practitioner. Same chair.

Unspoken Rules is where I sit as both a researcher and a practitioner of systems leadership. The thinking is grounded in a 2022 master's thesis on systems leadership in South African organisations. The practice is grounded in years of building programmes, facilitating teams, and working alongside corporates, NGOs, and creative communities — including In Good Company, my creative home championing microcultures in Cape Town.

Most leadership writing comes from somewhere else — Boston, London, the Valley. I write from inside post-traumatic colonialism, SETA politics, and the most unequal society on the data. That specificity is the work.

Outcomes are shaped by codes, not effort. Systems leadership is the discipline of reading the codes — and choosing where to move.

Head, Heart, Hands — the lens behind the practice.

One lens, three angles. Used for pattern recognition and connection recognition — the work of reading a whole, not just managing a part.

Head

The thinking. What does the system actually look like? Who's in it, what's flowing between them, and where is it stuck?

Heart

The behaviour. What codes, fears, loyalties, and beliefs are shaping how people move inside the system?

Hands

The action. Where is the leverage point? What's the smallest move that shifts the most — and who's positioned to make it?

Head + Heart + Hands  ×  Systems Leadership  =  pattern and connection recognition

Thinking tools behind the method.

Every session draws on established frameworks from systems thinking, developmental psychology, and organisational change. These are not decorative — they are the analytical tools we use to locate leverage and design coherent responses.

Framework 01
Head · Heart · Hands
Unspoken Rules methodology
A whole-person change model that sequences cognitive reframing, identity shift, and practical action — in that order, because order matters.

Six Conditions for Systems Change
Kania, Kramer & Senge · 2018
Structural, relational, and transformative levers for change. The transformative layer — mental models — is where most interventions fail to reach.

Framework 03
Systems Mapping: The Iceberg Model
Systems Thinking tradition
Most organisations react to events. This model locates the structures, relationships, and mental models that generate those events — the invisible root causes.

Framework 04
Maslow's Hierarchy of Needs
Abraham Maslow · 1943
Used in this work to understand what a mental model is protecting — safety, belonging, esteem — which determines what it takes to shift it without destabilisation.

Culture by Design.

Four offerings. One premise: most organisations manage symptoms, not the system underneath them.

Diagnostic · Teams & Organisations

Retention Diagnostic

For HR Directors and People leads who know people are leaving but can't name the real reason.

Your exit interviews are giving you the polite version. This diagnostic goes underneath — mapping the invisible rules shaping how people move through your organisation, and identifying where the leak actually is.

You leave with: a clear map of what's driving attrition and the specific intervention point where the work needs to happen. Timeline: 3–4 weeks.

Leadership Development · Managers

Leading from the Root

For senior managers who've tried everything at the surface level and know the problem runs deeper.

Most leadership development works at the level of behaviour. This programme goes to the system underneath — teaching you to read the whole before acting on any part of it. Head, Heart, Hands: see it, understand it, move it.

You leave with: a documented system map, named patterns, and one grounded move that shifts the culture — not just the conduct.

Organisational Design · People & Talent

Early Career Integration Design

For talent and people leads losing graduates in year one despite investing in recruitment.

Not a workshop for your graduates — a design process for your organisation. We map the system a graduate lands in on day one, find the gaps between what you assume and what you've shown, and redesign that system so the investment you made recruiting them doesn't walk out at 18 months.

You leave with: a redesigned integration pathway your organisation owns and can repeat with every new cohort.

Facilitation · Culture & OD

Cross-Generational Culture Facilitation

For culture and transformation leads navigating generational friction no one wants to name out loud.

The tension between generations in SA workplaces isn't a personality clash — it's two sets of unspoken rules colliding in the same room. This is a structured facilitated process to get that conversation out of the hallway and into the room, where it can actually be worked with.

You leave with: a shared language for what's been unspeakable, and a foundation for culture that both generations helped build.

What people say
"She always went out of her way to ensure that we understand the work and what was expected of us. Not only was she a good lecturer — she was a genuinely nice person as well."

Have a system you'd like to read together?

Whether it's a team, an organisation, a research question, or your own career — if there's a pattern worth surfacing, I'd like to hear about it.
