## What is Lean?

Find the waste in any process, and prove what fixing it is worth.

Lean diagnostics usually need a consultant and weeks of workshops. Lean by STRASYS lets the process owner do it: map the steps, and the app shows the waste, sizes the savings and opens an improvement project for every step that needs one.

Built for process owners, operations managers and executives who need Lean results without Lean training. Full English and Turkish interface.

30-day free trial with every feature and unlimited processes, no credit card required. A fully worked example process is included.

WHY OPERATIONS TEAMS USE IT
• Waste made visible, step by step, in your own numbers.
• Headcount savings calculated from your measurements, not estimated.
• Improvement projects opened automatically where needed.
• A before and after scorecard you can show the board.

MAP ANY PROCESS IN MINUTES
A three-step form (Definition, Shift, Demand) takes staff, shifts, work and break times, production and demand, with Now and Target side by side and a live takt time. Add each step in sequence and classify it as Value-Added, Incidental or Waste.

CHARACTERIZE AND MEASURE
Mark each step as Stable, Bottleneck, Defect, Overburden (Muri), Unevenness (Mura), Process Optimization or Standardization Issue, grouped by priority: Critical, High, Medium or No issue. Enter current and target Time, Distance and Inventory, and pick a Potential Solution from the built-in library of 28 Lean tools.

IMPROVEMENT PROJECTS, GENERATED FOR YOU
Every kept, non-stable step becomes an improvement project, carrying the Potential Solution you picked: Bottleneck Analysis, Poka-Yoke, Standard Work, Heijunka and more. Track status, progress and notes. Root-cause analyses are listed on the project and step cards. A process is complete when every project reaches 100%.

HEADCOUNT SAVINGS
Lean calculates the Optimum HC Index (the staff the process needs today), the staff needed after improvement and the headcount freed once every project reaches 100%: your ROI case. Enter an average yearly cost per person to see it as money per year.

BEFORE / AFTER SCORECARD
Six dimensions side by side: Total Time, Value Time, Incidental Time, Waste Time, Distance and Inventory, with colour-coded priorities and a before-to-after cycle-time chart.

SOLUTIONS CENTER
24 structured problem-solving methods (5 Whys, Fishbone, A3, 8D, FMEA, Pareto and more) with a Method Advisor that suggests methods for your problem.

DASHBOARD, ANALYTICS AND SHARING
Organisation-wide totals: processes, projects, headcount freed, cycle-time reduction and a people performance ranking. Share any process as a read-only link: no account needed, expires after 30 days, revocable any time.

6 STANDALONE LEAN TOOLS
Stopwatch for time studies, 7 Muda waste calculator, OEE, 5 Whys, Takt Time and 5S Audit.

LEARN AS YOU GO
A Knowledge Center with visual guides to the Lean tools and methods, a setup guide and a guided tour on the real screens.

SECURITY AND PRIVACY
