How to Build a Leadership Development Strategy: A Guide for HR Leaders Starting From Scratch

A five-step framework for designing leadership development that actually produces results, grounded in research and practice.

If you are the HR leader responsible for your organization's people strategy, and you have arrived at the recognition that you need a coherent approach to developing your leaders, you are already ahead of most of your peers. Research from DDI shows that most organizations have leadership development activity without a leadership development strategy. They have workshops, the occasional coaching engagement, and a budget line. What they do not have is a deliberate answer to the question of what kind of leadership their organization actually needs, and a plan for producing it at scale.

You already know what that gap costs. Gallup's research is unambiguous on this: managers account for roughly seventy percent of the variance in team engagement. When leadership development is ad hoc, engagement softens, good managers leave, and problems that should be resolved at the middle migrate upward until they sit on the desk of someone too senior to hold them. The people with the most potential quietly decide their growth will happen somewhere else.

The question is where to start. The answer is not to choose a training provider. It is to recognize that what you are building is not a program — it is a leadership culture. Programs are the instruments. Culture is the thing being built. Getting that order right is what separates organizations whose leadership development produces results from those whose investment disappears into the calendar.

Here is the sequence that works, and what shifts when an experienced partner is working alongside you.

Step 1: Diagnose Your Current Leadership Culture Before You Design Anything

Most organizations skip this step. They feel the pain, identify a plausible solution (usually a training program) and commission it. Then they are surprised when it does not move the needle.

Begin instead by understanding what is actually happening in your leadership culture right now. Where are decisions getting stuck? Where is accountability drifting upward? What patterns are your leaders showing under pressure, and what unspoken norms shape how people lead here? This is not a climate survey. It is a behavioural diagnosis of the patterns producing your current results.

A leadership consultant's first contribution is the diagnostic lens. An outside partner sees patterns that are invisible from inside the system: the cultural defaults everyone has adapted to and therefore stopped noticing. They bring frameworks for making sense of what they see, and the willingness to name it clearly.

Step 2: Clarify What Good Leadership Means in Your Organization

Before you design anything, you need an explicit, shared answer to a specific question: what does good leadership look like here, and why does it matter to our strategy? There is no generic answer, and organizations that try to use one end up with programs that feel imported rather than built.

This is not a competency list. It is a philosophy of leadership grounded in your organization's context: the challenges it faces, the culture it is trying to build, the outcomes it needs to produce. It should answer both the practical question (what do leaders need to do?) and the cultural one (what kind of environment should leaders create for their teams?). Amy Edmondson's research on psychological safety, reinforced by Google's Project Aristotle study of high-performing teams, makes clear that the environment leaders create is not incidental to performance, it is the single strongest predictor of it.

An outside partner helps you articulate this clearly. Left to internal conversations alone, the definition of good leadership tends to be either too generic to be useful or too idealized to be operational. A consultant pushes you toward specificity, tests your articulation against what your organization is actually asking of its leaders, and helps you ground it in language that people can act on.

Step 3: Design the Conditions That Make Development Work

The biggest mistake in leadership development is treating it as content delivery. The research is consistent: the widely adopted 70-20-10 model holds that roughly seventy percent of leadership development happens through stretch experiences, twenty percent through relationships and feedback, and ten percent through formal learning. If your strategy is primarily a training calendar, ninety percent of the actual development mechanism is missing.

Designing conditions means asking: what experiences will stretch our leaders in the right directions? What psychological safety do they need to take the risks that development requires? What structures (e.g. meeting rhythms, decision rights, performance conversations) will reinforce the behaviours we are trying to grow, rather than quietly punishing them? What coaching and feedback loops will help them integrate what they are learning? For senior leaders especially, one-on-one coaching is often where the real integration happens: it's the space where a leader can work through what the program is surfacing without an audience, and where the behavioural shifts tend to stick.

This is where consultants add some of their most durable value. Designing those conditions well often means bringing in someone to facilitate the conversations themselves: a leadership program that's delivered by an outside practitioner gives participants permission to engage differently than they would with an internal facilitator, and gives the organization an outside read on what's actually happening in the room.

Designing development conditions requires thinking across individual behaviour, team norms, and organizational structures simultaneously. Most internal HR functions are stretched across too many priorities to hold all three. An external partner brings the design capacity and the accumulated pattern recognition from having done this work across many organizations.

Step 4: Start With a Defined Cohort, Not the Whole Organization

One of the most common reasons leadership development strategies stall is that they try to do too much at once. Attempting to develop every leader simultaneously produces diluted programs, stretched delivery, and no clear signal of what is working.

Start with a defined cohort — most often senior leaders or a specific layer of leadership where the leverage is highest — and build from there. A focused cohort allows you to design with depth, measure results more precisely, and create visible proof points that build internal support for expanding the work. It also allows the people going through the program to develop together, which research on cohort-based learning consistently shows deepens and sustains the impact.

A consultant helps you identify the right cohort, sequence the rollout, and design for the ripple effects: how development at one layer creates the conditions for development at the next. This kind of phased design is difficult to do internally because it requires holding both the near-term program and the longer-term culture shift in view simultaneously.

Step 5: Build Measurement In From the Start

Organizations that add evaluation as an afterthought get anecdotes. Organizations that design measurement in from the beginning get data that justifies continued investment and sharpens the work over time.

Define, early, what success looks like at three levels:

1. Individual behaviour change

2. Team-level indicators (engagement, retention, quality of decisions), and

3. Organizational outcomes (strategic execution, readiness for growth).

   
   

You will not get clean attribution on all of these (no leadership development program does) but having the measurement architecture in place from the start is what makes it possible to demonstrate impact credibly to your executive team and board.

An outside partner brings both the measurement frameworks and the objectivity to tell you honestly what is working and what is not. That honesty is difficult to generate internally, where evaluation of a program often becomes evaluation of the person running it.

The Shift That Changes Everything

The HR leaders who build durable leadership development strategies share one thing: they stop thinking of this work as program delivery and start thinking of it as culture design. The programs still matter, and the training still happens. But they are instruments in service of a larger intent: the intentional design of a leadership culture where people do their best work, psychological safety is the default, and the organization becomes genuinely ready for the growth and change ahead.

This is the work I do with clients: helping HR leaders move from reactive, fragmented development activity to a coherent, intentional leadership strategy, designing and delivering programs that build real capability at the senior level, and coaching the leaders who need to do their own growing alongside their teams.

Frequently Asked Questions About Building a Leadership Development Strategy

How long does it take to build a leadership development strategy?

A credible leadership development strategy takes roughly three to six months to design and another twelve to eighteen months to implement in a way that produces visible cultural change. The design phase (diagnosis, clarifying your leadership philosophy, and building the roadmap) is typically the shorter stretch. The longer horizon is the implementation, because culture shifts require sustained behaviour change across multiple layers of the organization. Be cautious of any partner or internal plan that promises transformation in ninety days. What you can achieve in ninety days is clarity, alignment, and a well-designed first cohort.

How much should we budget for leadership development?

Benchmarks vary widely by industry and organization size, but a useful anchor is that organizations serious about leadership development typically invest between one and three percent of total payroll annually in leadership and management development. For a defined senior cohort, per-leader investment commonly falls in the range of five thousand to twenty thousand dollars annually, depending on the depth of coaching, assessment, and programming involved. The more important question than the absolute number is whether the investment is strategic or scattered. A smaller budget spent on a coherent program for a defined cohort will almost always outperform a larger budget spread thinly across disconnected activities.

Should we build our leadership development program internally or hire a consultant?

The answer is almost always both, and the question is really about sequencing. An external partner brings diagnostic capacity, design expertise, frameworks honed across many organizations, and the objectivity to name patterns internal teams have stopped seeing. Internal HR and L&D teams bring organizational context, relationships, and the continuity to sustain the work over time. The strongest strategies are designed with an external partner in the early stages (diagnosis, philosophy, architecture) and then delivered with a blend of external facilitation and internal ownership. Attempting to design the whole strategy internally is where most organizations get stuck, because the people closest to the culture have the hardest time seeing it clearly.

How do we measure the ROI of leadership development?

Measure at three levels, and define your metrics before you start.

1. At the individual level: track behaviour change through tools like leadership assessments, three-sixty feedback, and structured self-reporting.

2. At the team level: track indicators like engagement scores, retention of high performers, internal promotion rates, and the quality of decisions being made at the middle of the organization.

3. At the organizational level: track the business outcomes your strategy was designed to support: strategic execution, client outcomes, financial performance, readiness for growth.

Clean attribution is difficult because leadership development is one variable among many, but triangulating across these three levels gives you a credible and defensible story about impact.

When is the right time to start building a leadership development strategy?

The right time is before the gap becomes a crisis. Most organizations begin this work reactively: after losing a key leader, after an engagement score drops, or after a period of growth has outpaced the leadership bench. Starting earlier is significantly easier than recovering later. If you are asking the question at all, that is usually the signal. The cost of waiting is not just the absence of development; it is the continued accumulation of leadership patterns that will become harder to shift the longer they go unaddressed.
