Calculating Cost Savings in UX with Keystroke-Level Modeling is a concise, practical guide for UX designers, and product managers who want to prove the measurable value of design.
It introduces the TAPS Framework (Time × Actions × People × Salary)—a simple way to turn time-on-task data into real cost savings.
You’ll learn how to:
- Use Keystroke-Level Modeling (KLM) to quantify efficiency gains in seconds, not opinions.
- Apply the TAPS method to translate usability improvements into ROI that stakeholders understand.
- Compare old and new workflows to show how design changes reduce wasted effort.
- Manage uncertainty with real analytics, validation testing, and practical formulas.
This 16 page ebook bridges the gap between usability testing and business impact, giving you a toolkit to make every design decision defensible—with numbers that speak the language of executives.
Whether you’re auditing a process, pitching a redesign, or justifying a feature, this guide shows how small interface changes can produce measurable time and cost savings at scale.
