The 70-20-10 rule is a familiar reference in leadership development proposals. Before accepting a program because it uses those numbers, ask what they describe and what work the proposal actually supplies. A diagram showing three percentages is not a delivery plan, a budget or evidence that a participant has learned a leadership practice.
Editorial note: This is AI-assisted buying guidance based on the official CCL explanation linked below, viewed October 22, 2026. The application and company example are our editorial illustrations. We have not reviewed the underlying research studies or tested a 70-20-10 program, and we do not claim that Lean Leaders Plus supplies a fixed package using this model.
What does 70-20-10 mean in leadership development?
The Center for Creative Leadership’s 70-20-10 explanation, published April 24, 2025, describes a guideline emerging from its Lessons of Experience research on how executives develop through experience. It associates 70% with challenging assignments, 20% with developmental relationships and 10% with formal learning. Those are the source’s categories, not proportions measured in your proposed program.
CCL also emphasizes that experiences differ in their developmental value and that formal learning can strengthen learning from work and relationships. Read that fuller explanation before interpreting the small course percentage as a reason to remove instruction. We use the framework here to organize buying questions, not to forecast a particular employee’s learning.
Do not turn the percentages into a fee schedule
Our buying interpretation is straightforward: the three learning categories do not tell you how a supplier’s charges, participant hours or internal support costs should be divided. A demanding work assignment may need preparation and skilled review. A short course may supply a method that the manager then uses over several months. Their costs and elapsed time describe different things.
If a proposal presents a 70-20-10 budget, ask how it was constructed. What does each line buy, who delivers it and which organization supplies the work opportunity? Do not assume that an activity costs nothing because it happens during normal work, or that a course deserves only 10% of the fee because coursework is the smallest category in the model.
Ask how the three parts connect
A provider should be able to describe a suitable challenge, the people who support learning from it and the formal input that helps the participant attempt it. The useful test is the connection. A project with no clear development purpose, an unprepared mentor and an unrelated course do not become a coherent program because they fill three boxes.
The leadership program-design guide explains how prerequisites, assignments and feedback can form a sequence. Apply that check to a 70-20-10 proposal: what does the participant need before the assignment, what will they try, who helps them examine the attempt and what happens next? Ask for one complete participant path rather than a list of available activities.
Fictional example: prepare a resource recommendation
Imagine a newly appointed department manager preparing a first quarterly resource recommendation. The organization has already defined the manager’s decision scope and the authorized approval route. The learning challenge is to explain competing demands and the reasoning behind a recommendation, not to acquire permission to spend money or change policy.
A short learning session could introduce a way to compare the options. An appropriate work assignment could be drafting the recommendation using approved information. A colleague with relevant operational or financial understanding could discuss the assumptions and give feedback before the manager revises the draft. The sponsor still makes the decisions reserved to that role.
The buyer’s questions are concrete: Is this a suitable challenge for that manager? Can the reviewer make time and examine the reasoning credibly? Does the formal input address what the manager needs to attempt? What will be reviewed after the next appropriate recommendation? The example shows possible connections, not an endorsed CCL curriculum or a reported client result.
What should a proposal make explicit?
Ask the supplier to separate what it provides from what your organization must arrange. For the challenge, name the intended practice, prerequisites and authorized work opportunity. For developmental support, name the reviewer’s role and expected involvement. For formal learning, identify the relevant instruction and practice rather than relying on a topic label.
Then examine the transitions. Who notices when the work opportunity is delayed? What happens if the reviewer cannot participate? Which part of the proposal changes if the participant needs instruction before attempting the assignment? Keep those questions in the delivery plan rather than assuming the percentages settle them.
Review learning, not compliance with a diagram
At a review, ask what the manager attempted, what feedback they considered, how their reasoning or practice changed and what remains unresolved. Completing an assignment or logging mentor hours does not by itself establish that learning occurred. Nor does an operating result establish that the program caused it.
The training-transfer follow-up plan helps specify a participant-manager review. Use an appropriate work example and agreed responsibilities rather than calculating a personal 70-20-10 score. The purchasing decision is whether the connected work and support address the development need, not whether a calendar looks mathematically balanced.
