    TWO BASIC STEPS IN THE DIAGNOSTIC

    Build basic fact base Identify major improvement levers/bottlenecks

    Pareto charts Capacity balance

    1) Structure and focus the problem

    Further breakdown losses into sub-components

    Drive to root causes Build draft value driver tree and identify KPIs

    2) Dig into the vital few sub -issues

    The vital few issues and their causes, that whenresolved, will meet the project improvement target!

    WHAT YOU GET DIAGNOSTIC END-PRODUCT

    Clear view of the 3-5 issues that needto be resolved first the vital fewfocal points for idea generation

    Issues specific enough to begin

    identifying actionable solutions (vs.more issues)

    Confidence that solving the vital fewwill exceed the target

    Agreement with key projectsponsors/mine managers on priorities

    Absolutely criticalfor a successfulstep 2

    There is atendency to

    cheat step 1

    Cheating leads to: Solving

    symptoms vs.causes

    Wasted time,frustration
