Lean and continuous improvement

About this practice suite

This suite prepares candidates for lean and continuous improvement selection in the manufacturing, production, maintenance, and quality sector with 5 skill areas: problem solving, data interpretation, planning and scheduling exercises, critical thinking and numerical reasoning. Every question was written by Novus editors for this suite — none are taken from live or leaked exams — and the full bank holds 52 scored questions across three modes, plus 8 reserve questions used to vary repeat attempts. Answer keys never ship to the browser: your answers are scored server-side, and results stay on your device.

Skills this suite practises

• Problem solving — Selecting methods, combining information, troubleshooting, and reaching practical solutions.
• Data interpretation — Tables, charts, graphs, dashboards, trends, comparisons, and evidence-based conclusions.
• Planning and scheduling exercises — Resources, dependencies, deadlines, constraints, and contingency planning.
• Critical thinking — Evaluating evidence, assumptions, arguments, credibility, and alternative explanations.
• Numerical reasoning — Arithmetic, fractions, percentages, ratios, rates, estimation, word problems, and number relationships.

Sample questions from the guided bank

Two of the 10 guided-practice questions, shown exactly as they appear in a session. Answers and explanations are not printed here — keys stay on the server — so open guided practice to answer them and see how you did.

1. A lean / continuous-improvement practitioner's primary duty on shift is to:

   • A. Ignore alarms to keep output high
   • B. Perform lean and continuous improvement tasks safely within approved procedures and limits
   • C. Bypass interlocks casually
   • D. Rewrite safety rules mid-shift alone

2. You notice an unsafe condition during lean and continuous improvement work. Best first action?

   • A. Hide the issue until end of shift
   • B. Continue and hope it clears
   • C. Stop or pause the hazard path, warn others, and escalate per procedure
   • D. Disable the related alarm permanently

Practice modes and timing

Guided practice is untimed-feeling and instructional; the mini-test is a short timed check; the full simulation mirrors a complete sitting. All three draw on separate question sets, so moving up a mode never repeats what you practised.
