HKSM

An adaptive way of developing where the product is delivered in successive pieces, each adding new features, until the result has all the capabilities needed to be called complete.

Key Points

• Delivers working slices that expand functionality over time.
• Each increment is planned, built, tested, and potentially releasable.
• Stakeholder feedback after each increment helps shape upcoming work and priorities.
• Different from iterative: incremental adds new features; iterative refines what already exists; they are often combined.

Example

A team building a customer portal releases Version 1 with login and profile, Version 2 adds order history, Version 3 adds returns and refunds, and Version 4 adds loyalty points. Each release is usable and adds new capability until the portal meets the defined completion criteria.
