LPSCE study plan

LPSCE · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Lean Principles and Waste Elimination

  • Classify each of the eight Lean wastes (defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion, extra processing) using at least two workplace or case examples per waste type

  • Calculate takt time, cycle time, and lead time for three worked numerical scenarios and explain how each metric drives waste-elimination priorities

  • Draw a current-state value stream map for a process you know well, labeling process boxes, inventory triangles, information flow, and lead-time ladder

  • Differentiate push versus pull scheduling and identify where a kanban or supermarket buffer would reduce overproduction in your mapped process

  • Explain how 5S, standard work, and poka-yoke each attack a specific waste category, citing one concrete countermeasure per tool

Your checkpoint

A one-page current-state VSM of a real or realistic process with a waste-tally table listing at least 10 identified wastes, their category, root location, and a proposed countermeasure

Week 2

Six Sigma Fundamentals and DMAIC

  • Sequence the five DMAIC phases and state the entry and exit criteria (tollgates) that gate movement between them

  • Distinguish common-cause from special-cause variation and select the correct response (process change versus local action) for six given scenarios

  • Compute DPMO, rolled throughput yield, and sigma level from defect and opportunity data, showing the conversion steps

  • Compare Lean, Six Sigma, and Lean Six Sigma on problem type, typical tools, and time horizon, and justify which approach fits three described projects

  • Map each DMAIC phase to the primary tools used within it (charter and SIPOC in Define, MSA and capability in Measure, and so on) to build a working mental model of the roadmap

Your checkpoint

A DMAIC roadmap one-pager with phase-by-phase deliverables, tollgate questions, and a worked sigma-level calculation checked against a published sigma conversion table

Week 3

Define Phase: Project Chartering and Voice of the Customer

  • Draft a complete project charter containing problem statement, business case, goal statement (SMART), scope with in-scope and out-of-scope boundaries, team roles, milestones, and expected financial benefit

  • Rewrite three vague problem statements into measurable ones that specify metric, baseline, target, and time frame without prescribing a solution

  • Build a SIPOC for a chosen process with at least five rows and validate that inputs and outputs are specific and measurable

  • Translate raw voice-of-the-customer statements into CTQ requirements and prioritize them using a Kano or CTQ tree structure

  • Identify stakeholders and their influence and interest, then select an appropriate engagement approach for each quadrant

Your checkpoint

A full project charter plus SIPOC and CTQ tree for one realistic improvement project, with a stakeholder map and a one-paragraph business case

Week 4

Measure Phase: Data Collection, MSA, and Process Capability

  • Distinguish continuous from discrete data and select appropriate measurement scales and summary statistics for each

  • Design a data collection plan specifying operational definitions, sampling strategy, sample size rationale, and data stratification factors

  • Compute and interpret Gage R&R results, deciding whether a measurement system is acceptable using the 10/30 percent rule for study variation and the precision-to-tolerance ratio

  • Assess attribute agreement and explain why kappa matters for pass/fail inspection data

  • Calculate Cp, Cpk, Pp, and Ppk from given summary statistics and interpret each against specification limits, explaining what each index reveals about centering versus spread

Your checkpoint

A measurement systems analysis report containing a data collection plan, a completed Gage R&R calculation with interpretation, and a capability analysis of one process with Cp/Cpk plus a written verdict on whether the process can meet specification

Week 5

Analyze Phase: Root Cause Analysis and Hypothesis Testing

  • Build a cause-and-effect diagram and a C&E matrix to narrow a long candidate-cause list to the few variables worth testing

  • Construct and interpret a multi-vari chart and stratification analysis to separate positional, cyclical, and temporal variation

  • Select the correct hypothesis test (one-sample t, two-sample t, paired t, one-way ANOVA, chi-square, or regression) for eight stated questions and justify each choice

  • Interpret p-values, confidence intervals, and statistical versus practical significance, and explain the risks of Type I and Type II error in a project context

  • Verify a root cause using at least two independent evidence sources before moving to solution design, and document the verification logic

Your checkpoint

A root-cause analysis package with fishbone, C&E matrix, stratification chart, and at least two hypothesis tests run on sample or simulated data, concluding with a verified root cause and its supporting evidence

Week 6

Improve Phase: Solution Design, Lean Tools, and Pilot Testing

  • Generate and screen solution candidates using brainstorming plus impact/effort and Pugh matrix selection against defined criteria

  • Apply 5S, kaizen event design, standard work, and error-proofing to a specific process step and predict the resulting waste reduction

  • Conduct a failure mode and effects analysis with severity, occurrence, and detection ratings and prioritize actions by risk priority number

  • Design a pilot including success criteria, sample size, duration, control group or before-after comparison, and a decision rule for scale-up

  • Plan a 5S or standard-work implementation with visual controls and a documented before/after comparison method

Your checkpoint

A solution design package containing a Pugh matrix of at least three options, an FMEA with prioritized actions, and a pilot plan with measurable success criteria and a go/no-go decision rule

Week 7

Control Phase: SPC, Standard Work, and Sustainment

  • Construct X-bar and R, individuals and moving range, p, and u control charts from given data and calculate control limits correctly

  • Interpret control chart patterns including points beyond limits, runs, trends, and stratification, and distinguish these from specification-limit violations

  • Write a response plan for out-of-control signals naming who acts, what they check, and the escalation path

  • Document standardized work with a control plan, reaction plan, and visual management board that sustain the gains

  • Design a control and monitoring plan including ownership, audit frequency, and a plan for handing the improved process to the process owner

Your checkpoint

A control plan for the improved process with at least one correctly constructed control chart, documented response rules, standardized work documentation, and a named process owner with audit cadence

Week 8

Project Management, Team Leadership, and Change Management & Lean Principles and Waste Elimination & Six Sigma Fundamentals and DMAIC

  • Build a project plan with work breakdown structure, critical path, resource needs, and a risk register with mitigations

  • Explain team development stages and select leadership actions appropriate to forming, storming, norming, and performing phases

  • Apply a change management model to anticipate resistance, identify sponsors and resistors, and design communication and training tactics

  • Run a full timed practice exam under test conditions, then analyze missed questions by domain to target the weakest areas

  • Rehearse the project story end-to-end (charter through control) as if presenting to a sponsor, and close remaining gaps in Lean and DMAIC fundamentals

Your checkpoint

A complete project portfolio: final presentation deck covering charter, baseline data, root cause, solution, pilot results, control plan, and lessons learned, plus a scored practice exam with a written remediation list by domain
