Category: Business – This Explainer

Lean manufacturing organizes work around customer value, flow, pull, quality, and continuous improvement. This explainer covers waste, value streams, small batches, standard work, people, and resilience.

Six Sigma is a disciplined improvement method focused on variation and defects. This explainer covers customer requirements, DMAIC, measurement systems, root causes, controls, roles, and the need for context.

The Theory of Constraints treats system throughput as limited by a small number of constraints. This explainer covers identifying, exploiting, subordinating, elevating, and reassessing the constraint.

Inventory carrying cost includes capital, storage, service, shrinkage, and obsolescence tied to stock. This explainer covers cost components, carrying rates, average inventory, decision use, and hidden assumptions.

Batch size shapes setup frequency, inventory, lead time, flexibility, and defect exposure. This explainer covers economic tradeoffs, queues, changeovers, demand variability, and why the largest run is not always cheapest.

Process mapping makes the real flow of work visible. This explainer covers boundaries, current and future states, roles, handoffs, queues, exceptions, evidence, and the limits of diagramming.

Root cause analysis moves beyond the immediate symptom to identify controllable system causes. This explainer covers containment, evidence, causal chains, human factors, corrective action, and effectiveness checks.

Continuous improvement builds an operating habit of identifying problems, testing changes, measuring results, and standardizing what works. This explainer covers priorities, PDSA cycles, frontline ownership, metrics, and sustainability.

Quality management coordinates policies, processes, measurement, control, and improvement so outputs meet requirements. This explainer covers customer needs, prevention, variation, audits, corrective action, and culture.

Demand forecasting converts evidence about customers, markets, and history into planning ranges. This explainer covers qualitative and quantitative methods, hierarchy, seasonality, promotions, error, and decision use.

Lead time measures how long a process takes from request or release to delivery. This explainer covers processing, queues, transport, approvals, variability, promised versus actual time, and improvement.

The reorder point is the inventory position that triggers a new order. This explainer covers lead-time demand, safety stock, inventory position, service targets, seasonality, and changing parameters.
