Staircase Ascent Logic Model
Brief
The Staircase Ascent Logic Model is a visual framework that maps an organization's theory of change as a climbing staircase, moving step by step from Inputs up to Impact. Each stage sits on an ascending "stair," making the progressive build of value immediately visible. The five steps are: Inputs, Activities, Outputs, Outcomes, and Impact. Below the staircase, space is provided for Assumptions and External Factors that may influence results.
Who can use it
L&D teams, HR strategists, program designers, nonprofit leaders, corporate trainers, grant applicants, and anyone building a case for how invested resources ladder up to measurable change. It suits leadership development programs, capacity-building initiatives, training cohorts, and any initiative where progress is sequential and cumulative.
How to use it
Begin at the bottom-left stair (Step 1 · Inputs) and list resources committed—staff, budget, tools, partnerships. Move up to Step 2 · Activities and describe what will be done with those resources. Step 3 · Outputs captures direct, countable deliverables. Step 4 · Outcomes records short/medium-term changes observed. Step 5 · Impact at the top captures long-term transformation. Fill in the Assumptions and External Factors boxes at the base to document conditions the logic depends on and forces outside your control. Revisit the staircase as the program evolves.
About the example
The included example illustrates the "NUST Emerging Leaders Ladder." Inputs include an HR L&D team plus external coach, a $60,000 budget, and a 360-degree review tool. Activities cover a 6-month leadership curriculum, peer coaching circles, and stretch-assignment rotations. Outputs show 45 employees enrolled, 90 coaching sessions delivered, and 12 capstone projects completed. Outcomes report promotion-readiness up 78%, 90% manager satisfaction, and 20% higher cohort retention. Impact: a stronger internal leadership pipeline and lower external-hire cost for senior roles. Assumptions note that managers must release staff time and the coaching partner remains available. External factors include annual budget cycle approval and broader attrition trends in senior roles.
