In practice, that means removing unnecessary steps, features, and jargon, and keeping the parts that solve the customer’s or the business’s real problem. KISS is a decision rule, not a promise that simpler is always better.
What the phrase means
KISS is most often expanded as “Keep it simple, stupid.” Business.com also uses the gentler form “Keep it simple and straightforward,” and describes the business application as not making things more complicated than they need to be. For a general business audience, the softer wording carries the same meaning without the blunt phrasing, and it is the version worth using in internal documents and client-facing material.

The principle is not limited to writing. The same source applies it to business processes, systems, product development, and marketing communication. The common thread is that complexity is a cost, and every layer of it should justify its place.
Where KISS applies inside a business
The principle shows up in five recurring areas. The table below lists what to look for in each and what the cited sources say about it.
#1 Best Overall
| Area | What to simplify | What the sources say |
|---|---|---|
| Operations | Unnecessary steps, duplicated work, and extra handoffs between people or teams | Business.com names removing unnecessary steps and redundancies as a direct application of KISS. |
| Project communication | The project vision, intended outcome, and business case | Dr Jim Dale, writing for the Association for Project Management on November 9, 2017, argues for a clearly explained vision and a business case in which benefits clearly exceed risks, costs, and timescales. |
| Products and services | Features that do not serve the customer’s main problem | Business.com recommends concentrating product development on core features, then checking whether each added feature delivers clear value. |
| Organization design | Overlapping product lines, customer segments, locations, and markets | Kellogg School of Management, Northwestern University, describes these patterns as common sources of complexity in companies. |
| Leadership and information | Gaps in what people know about what the business is trying to achieve | In a September 1989 Harvard Business Review interview, Jack Welch linked organizational simplicity to clear communication and access to information. |
A practical way to apply it
Use the following sequence when deciding whether a process, offer, or message needs simplifying.
- State the customer need or business outcome the product, process, or message must serve.
- List every step, feature, choice, approval, and term currently involved.
- For each element, ask what it contributes to that outcome. Remove or combine the ones that add no clear value.
- Explain the resulting process or offer in plain language, and make ownership of each part explicit.
- Check with the people who use the system or receive the communication that the simpler version still meets the real requirement.
- Revisit the decision when the customer need, the risks, or business conditions change.
These steps are editorial recommendations drawn from the cited sources. They are not a tested method, and none of the sources reports a measured improvement from following them.
Where simplification goes wrong
KISS does not mean stripping out safeguards, necessary choices, or the information people need to make a sound decision. The test is whether a simplification preserves the function and meaning that matter. A step that looks redundant may be the control that prevents an expensive error.
Simplicity is not the same as having less
MIT Press, describing John Maeda’s work in The Laws of Simplicity, lists “Reduce” as his first law. The same description makes clear that simplicity is not “less just for the sake of less,” and it recognizes that some things cannot be made simple. A useful KISS review therefore asks what must remain, not only what can go.
Rank #3
Diagnose before cutting
Kellogg’s discussion notes that product lines, customer segments, and markets can accumulate into complexity. It does not establish that cutting any particular offering will improve a particular company’s results. Confirm what is redundant or burdensome, and understand why it exists, before recommending its removal. A product line that looks overlapping on a chart may serve a customer group that nothing else reaches.
What leaders have said about simplicity
Jack Welch addressed the idea at the scale of the whole organization. In a Harvard Business Review interview published in September 1989, he said: “For a large organization to be effective, it must be simple.”
Where the phrase comes from
The Kellogg School and the Association for Project Management both report that the phrase is commonly attributed to the U.S. Navy in the 1960s, with Kellogg specifying 1960. Both accounts are secondary, and the origin should be treated as the usual attribution rather than settled history. The meaning of the principle, not its exact birthplace, is what matters for business use.

Further reading
For a longer treatment of simplicity and complexity across business, technology, and design, MIT Press lists John Maeda’s The Laws of Simplicity. The book’s central framing, that simplicity has to be balanced against complexity, is the most useful counterweight to applying KISS as a blanket rule.
