Improve & Standardize

5S Workplace Organisation

Build a visual workplace standard, evaluate every 5S step and turn findings into a practical action plan.

Improve & Standardize

Kaizen Improvement Proposal

Structure a small improvement from current state through evidence, expected benefit, implementation tasks and follow-up.

Improve & Standardize

PDCA Improvement Cycle

Plan an improvement hypothesis, record execution, compare actual results with the target and decide what to standardise or revise.

Improve & Standardize

A3 Problem-Solving Report

Connect background, current condition, target, root-cause analysis, countermeasures and follow-up on one coherent management page.

Problem Solving & Quality

5 Why Root-Cause Analysis

Build an evidence-based cause chain from a precisely defined problem to a controllable process cause and corresponding corrective action.

Problem Solving & Quality

Ishikawa Cause-and-Effect Diagram

Explore possible causes systematically, organise them into meaningful branches and distinguish hypotheses from causes confirmed by evidence.

Problem Solving & Quality

Pareto Analysis

Rank loss categories, calculate cumulative contribution and focus improvement on the few categories that dominate the selected measure.

Problem Solving & Quality

Histogram & Distribution Analysis

Visualise the distribution of measured data, compare it with specification limits and detect spread, skew, multimodality or unusual values.

Problem Solving & Quality

Scatter Diagram & Correlation

Plot paired observations, estimate the strength and direction of association and reveal clusters, curvature or outliers that deserve investigation.

Problem Solving & Quality

Control Chart & SPC

Plot process data in time order, calculate control limits and distinguish common-cause variation from signals that require investigation.

Problem Solving & Quality

Poka-Yoke Error Proofing

Translate a specific error mechanism into prevention, detection or control concepts and evaluate them for reliability, response and new risk.

Problem Solving & Quality

Process FMEA Risk Analysis

Connect process functions, failure modes, effects, causes and current controls, then prioritise prevention and detection improvements with accountable actions.

Problem Solving & Quality

Muda Waste Analysis

Observe work, classify evidence across the eight wastes, estimate impact and convert the largest controllable losses into experiments or actions.

Process, Flow & Capacity

Process, Flow & Capacity

Process Flowchart

Build a clear sequence of activities, decisions, hand-offs and loops so the actual process can be discussed, checked and improved.

Process, Flow & Capacity

Process Mapping

Document activities with owners, inputs, outputs, time and value contribution to expose unclear responsibilities, delays and non-value-added work.

Process, Flow & Capacity

Value Stream Mapping (VSM)

Combine material flow, information flow, inventory, process data and timeline to understand end-to-end lead time and design a realistic future state.

Process, Flow & Capacity

Spaghetti Diagram

Trace real movement on a scaled layout, measure distance and frequency, and compare current and proposed routes before changing the workplace.

Process, Flow & Capacity

SIPOC Process Definition

Define suppliers, inputs, high-level process, outputs and customers to align scope and requirements before detailed mapping or problem solving.

Process, Flow & Capacity

Yamazumi Workload Chart

Stack work elements by station or operator, compare workload with takt time and identify overload, waiting and opportunities to rebalance work.

Process, Flow & Capacity

Production Line Balancing

Assign work elements to stations under takt, precedence and capability constraints, then compare efficiency, idle time and bottleneck risk.

Process, Flow & Capacity

Capacity & Production Balancer

Model daily and annual capacity, define fixed and variable capabilities, prioritise limiting factors and allocate compatible jobs to workplaces.

Process, Flow & Capacity

SMED Changeover Analysis

Record changeover activities, classify internal and external work, expose parallel opportunities and build a safer reduced-time standard.

Process, Flow & Capacity

Takt Time Calculator

Convert customer demand and net available production time into the required completion rhythm, then compare takt with cycle time and capacity.

Process, Flow & Capacity

Standard Work

Define the safest current best-known sequence, expected timing, standard inventory and key quality points so work can be trained, observed and improved.

Process, Flow & Capacity

Kanban Pull-System Sizing

Size a pull loop from demand, replenishment time, container quantity and justified safety factor, then define the signal and operating rules.

Process, Flow & Capacity

Just-in-Time Flow Assessment

Assess whether flow, takt, pull, levelling, quality and replenishment stability are ready to support lower inventory without increasing delivery risk.

Daily Management & Maintenance

Daily Management & Maintenance

OEE – Overall Equipment Effectiveness

Calculate Availability, Performance and Quality from transparent production data and trace the OEE gap to concrete loss categories.

Daily Management & Maintenance

Gemba Walk

Plan a respectful process-focused observation, capture facts and questions, recognise abnormalities and assign follow-up without turning the walk into an audit theatre.

Daily Management & Maintenance

Total Productive Maintenance (TPM)

Structure equipment losses, operator care, inspection standards, planned maintenance and improvement actions around the conditions required for reliable production.

Daily Management & Maintenance

Andon Response Design

Design call categories, triggers, ownership, target response, escalation and closure evidence so abnormalities receive visible and timely support.
