Zero-Based Budgeting vs. Capability-Based Planning: Cost vs. Value

Zero-Based Budgeting (ZBB) and Capability-Based Planning represent two fundamentally different philosophies of resource allocation that are frequently discussed separately — but are most powerful when combined. Zero-Based Budgeting requires every budget line to be justified from scratch each planning cycle, rather than using the prior year's budget as the starting point. It is a cost-focused discipline that challenges every expense and forces managers to justify why each activity should continue to be funded. Capability-Based Planning allocates resources based on the strategic importance and current maturity of organizational capabilities. It is a value-focused discipline that asks not just 'why does this cost exist?' but 'what capability does this investment build, and how important is that capability to our strategy?' The combination of the two creates a planning process that is simultaneously rigorous about cost (ZBB) and rigorous about value (Capability-Based Planning). When executed together, they prevent the common trap of cutting strategically critical investments while ensuring operational efficiency across all activities.
