What is TIMWOODS? The 8 Types of Waste Holding Your Small Business Back

The Situation

According to The Alternative Board (TAB) Business Leader Surveys, 84% of small business owners work more than 40 hours per week (63% work at least 50 hours a week and 25% work more than 60 hours). And the Slack/Salesforce Small Business Productivity Survey (2024) reports that small business owners lose an average of 96 minutes (1.5 hours) of productivity daily — the equivalent of three full weeks of lost time every year.

Drawing from multiple reports, one can conclude that small and mid-sized business owners are losing significant time and money to operational waste they often cannot name, feel emotionally overwhelmed by the daily grind of running their businesses, and are increasingly experimenting with AI tools — often without first diagnosing the underlying process problems those tools are meant to solve.

"Putting out one fire after another", "I can never get ahead because I'm always in crisis mode", "Overwhelmed", "Nothing happens unless I'm there", "I spend half my day on email" — this is how SMB owners typically describe their day. TIMWOODS is the framework that names what they're experiencing.

About the Framework

The TIMWOODS framework was born in post-war Japan as part of the Toyota Production System (TPS). At the time, Toyota couldn't compete with the massive budgets of American automakers. To survive, they had to be smarter. Under the leadership of Kiichiro Toyoda and Taiichi Ohno, the company pioneered a ruthless elimination of waste. What started on the factory floor eventually expanded into a global standard for operational efficiency across diverse industries. Today this approach is known as Lean — one of the most widely adopted process improvement methodologies in the world.

The 8 Types of Waste

Originally, there were seven types of waste — or Muda (any activity that consumes resources without creating value). In the 1990s, as Lean principles moved into the Western world, an eighth waste was added: the failure to use the creative potential of employees.

T — Transportation

Moving information, materials, or documents unnecessarily

What SMBs (small and mid-sized businesses) experience: Files transferred between departments that get lost. The same data re-entered into multiple platforms. Information stuck in email chains.

Evidence: "The typical office worker spends 10% of their time on manual data entry." Trades businesses specifically: "business owners waste time entering the same information multiple times."

I — Inventory

Excess stock, backlogs, over/under-ordering

What SMBs experience: Retail: stockouts costing sales; overstocked items tying up cash. Restaurant: food waste; surplus ingredients expiring. Service: backlogs of unprocessed orders.

Evidence: Pitfire Pizza uncovered a $55,000 annual loss from over-portioned mushrooms — identified and fixed in one month. The restaurant industry alone loses an estimated $3B/year to operational inefficiencies. A mid-sized retailer reduced stockouts by 40% and cut excess inventory by 25% after switching to an integrated inventory system.

M — Motion

Unnecessary physical or digital movement

What SMBs experience: Retail staff walking significant distances repeatedly. Teams switching between apps all day (context-switching). Employees searching for files across multiple locations.

Evidence: Context-switching between apps is consistently documented as a top time-waster. The average SMB owner switches between 4+ digital tools daily — each switch is a motion waste event.

W — Waiting

Delays caused by approvals, information gaps, or dependencies

What SMBs experience: Projects held up waiting for one person's approval. Customers waiting because internal processes don't move. Staff idle while waiting for owner decisions.

Evidence: 28% of small business owners cite "waiting for status updates" as a top time-waster. "Internal bottlenecks become external frustrations — customers waiting for contract signatures or refund approvals experience delays directly."

O — Overproduction

Producing more than needed, earlier than needed

What SMBs experience: Reports that nobody reads. Meetings held before decisions are ready. Inventory ordered before demand is confirmed.

Evidence: 96% of restaurant operators faced supply chain disruptions — many caused by over-ordering based on guesses rather than demand data. "Overproduction is the root waste — it cascades into inventory, transportation, motion, and waiting."

O — Overprocessing

More steps or effort than the customer requires

What SMBs experience: Multiple approval steps for simple decisions. The same data entered in three different systems. Overly complex processes that grew without design.

Evidence: Law firms: "billing creates persistent cost inefficiencies when time logging and document management are not integrated — invoice accuracy suffers, billable hours get missed."

D — Defects

Errors, rework, mistakes requiring correction

What SMBs experience: Orders entered incorrectly. Invoices with wrong amounts. Customer complaints caused by miscommunication. Work that needs to be redone.

Evidence: Restaurants: "When an ordering system doesn't integrate with POS, staff manually enter orders, mistakes pile up." Over 40% of workers spend at least a quarter of their workweek on manual, repetitive tasks — a significant share of which involves catching and fixing errors.

S — Skills

Underutilizing people's capabilities — wrong people on the wrong tasks

What SMBs experience: The owner doing tasks that an assistant or software could handle. Skilled staff buried in admin instead of high-value work.

Evidence: Lawyers spend 48% of their day on administrative tasks. As Michael Gerber put it in The E-Myth Revisited: "If your business depends on you, you don't own a business — you have a job. And it's the worst job in the world because you're working for a lunatic!"

Why Small Businesses Need This Most

TIMWOODS isn't just for giant factories. In fact, small businesses often have the most to gain:

Higher Stakes: While a 5% waste might be a rounding error for a large corporation, research shows SMBs lose 20–30% of their operational expenditure each year to rework, miscommunication, and fragmented systems — often enough to determine whether a business is profitable or not.
Agility: Unlike giant companies, you can identify a bottleneck on Monday and fix it by Wednesday. You don't need a three-year "transformation program." Process improvement at the SMB scale moves fast.
Proven ROI: Well-executed Lean programs in smaller companies average a 200% ROI within 12–18 months.

Real-World Applications

Professional Services: Waste here is usually "invisible." It looks like senior staff performing admin tasks (Skills) or projects waiting for a partner's signature (Waiting).
Healthcare: Focuses on reducing patient wait times and eliminating Defects like medication errors or coding mistakes.
Software/SaaS: In tech, "Inventory" is a massive backlog of half-finished features, and "Overproduction" is building tools that users never actually click on.
Retail & Hospitality: The biggest challenge is "Inventory" (dead stock) and "Overprocessing" (elaborate service steps that customers find annoying rather than helpful).

How to Improve Operations: The 3-Step Plan

Diagnose: Find the "Hidden Drains"

Stop guessing where the problems are. Start looking for "firefighting" moments. If you find yourself saying, "I have to fix this again," you've found a waste. Think of it as a quick operational waste audit — a structured look at your team's day that can reveal expensive, hidden patterns in about 10 minutes.
Fix: Streamline Before You Digitize

Never automate a broken process. If you put a computer on top of a mess, you just get a "digital mess." Simplify the workflow first — remove the extra approval layers and cut out the app-switching.
Automate: Scale with Intelligence

Once the process is clean, bring in the tools.
- Human-in-the-Lead: Use AI to handle the routine "drudge work," allowing your team to move up the value chain to focus on judgment and creativity.
- Continuous Improvement: Once automated, your systems should provide a feedback loop — helping you refine the process further as you grow. This is the essence of Lean thinking: not a one-time fix, but a continuous improvement cycle built into how your business operates.
