A HACCP plan is a written, site-specific system for identifying significant food safety hazards, setting critical limits, monitoring controls, and recording corrective action and verification.

A fish may be at home in water, but getting seafood safely from the water to a customer’s plate takes disciplined control. The same is true for every food operation. The CDC estimates that foodborne illness affects roughly one in six Americans each year, which is why hazard prevention must be planned rather than improvised.

Process control is the practice of measuring how a process performs, comparing the result with a defined standard, and correcting deviations before they create errors, risk, or waste. In industrial systems, that may mean regulating pressure or temperature. In business operations, it means keeping recurring work inside the limits your team has agreed to follow.

Your body does this constantly. When your temperature rises, it detects the deviation and responds by sweating until you return to a safe range. Organizations need the same feedback loop: a clear standard, reliable evidence, a way to spot exceptions, and corrective action that brings work back under control.

Business process testing (BPT) is the practice of checking whether an end-to-end business workflow produces the expected result across people, rules, data, and connected systems. End-to-end business process testing checks the whole process, not just one screen or software function.

Written processes should be updated, automated where appropriate, and reviewed for relevance as a company grows. Yet documentation alone does not prove a process works. In a 2016 Procesowcy study of 236 Polish organizations, 69% self-assessed at one of the two measured-process maturity levels, but verification placed only 4% at the highest measured-and-managed level. Business process testing closes that gap by checking the real flow, including handoffs, approvals, exceptions, and data transfers.

Failure Mode and Effects Analysis (FMEA) helps a team identify how a process, product, or service could fail, understand the effects, and prioritize preventive action before customers feel the impact.

The 2017 British Airways catastrophe shows why that discipline matters. An early estimate put the potential cost as high as £100 million, while IAG later reported an estimated gross cost of about £80 million. The IT outage disrupted tens of thousands of travelers and exposed how a single failure can travel through an interconnected operation.

Genchi Genbutsu is a Toyota problem-solving principle that means “actual place, actual thing.” It asks leaders to go to the source, inspect the real work or object, speak with the people closest to it, and verify facts before choosing a countermeasure.

Reports, dashboards, interviews, and AI summaries can reveal patterns, but each is an abstraction. Genchi Genbutsu combines those signals with firsthand evidence so a team can distinguish the condition it assumes exists from the one people actually experience.

DMAIC is a five-step, data-driven improvement cycle: Define, Measure, Analyze, Improve, and Control. Used in Six Sigma, it helps teams find and remove defects in an existing process.

This guide walks through each step, the measurements and tools used at each stage, and the controls that keep an improvement from slipping back.

Design for Six Sigma (DFSS) is a methodology for designing or fundamentally redesigning products, services, and processes so customer requirements and defect prevention are built in before launch. Applied well, Design for Six Sigma can supercharge your business by preventing costly design failures before they reach full operation.

DFSS is the umbrella approach. DMADV, Define, Measure, Analyze, Design, Verify, is one of its most common phase models. Use it when you are creating something new or overhauling a design. Use DMAIC when you need to improve an existing process with measurable performance data.

Lean management, Six Sigma, and Lean Six Sigma all walk into a bar. Lean orders a Scotch. Six Sigma orders bourbon. Lean Six Sigma orders a hot toddy. The bartender says, “So that will be a whisky, a whiskey, and a bit of both.”

The joke works because the methods are related, but they are not identical. Lean removes waste, Six Sigma reduces defects and variation, and Lean Six Sigma combines both goals. This guide maps nine practical Six Sigma tools and techniques to the Define, Measure, Analyze, Improve, and Control stages of the DMAIC framework.

Business risk is any event, condition, or decision that can stop a company from meeting its objectives. The risk may start inside the business, with people, systems, customers, competitors, or controls, or outside it, with disrupted supply chains, extreme weather, climate transition, and ecosystem loss.

Managing business risk means identifying exposure early, assessing likelihood and impact, assigning an owner, choosing a response, and collecting evidence that the control worked. This guide covers six direct business risks and the 3 main threats that can cascade through climate and nature. It also explains how you can manage each risk through controlled execution.

AS9100 is the internationally recognized quality management system standard for aviation, space, and defense organizations. The current published edition is AS9100 Rev D, aligned with IAQG 9100:2016 and built on ISO 9001:2015. It keeps ISO 9001’s quality management foundation and adds aerospace controls for product safety, operational risk, configuration management, supplier oversight, counterfeit-part prevention, and traceability.

Those controls are one part of a much larger safety system that also includes engineering, regulation, maintenance, training, and accident investigation. The results are striking: IATA recorded 51 accidents across 38.7 million flights in 2025, while an MIT analysis estimated one fatality per 13.7 million passenger boardings from 2018 through 2022. AS9100 matters because it makes disciplined quality work repeatable across a complex global supply chain.
