Interest in the possible applicability of TRIZ tools and techniques to the world of management and organisational innovation issues continues to grow. Theaim of this article is to place the 40 Inventive Principles of TRIZ in thecontext of this business environment. The format of the article is based closelyon an earlier text (1) in which examples of technical deployment of thePrinciples were given.
The 40 Inventive Principles provide innovators with systematic and potentmeans of breaking out of current paradigms into often exciting and beneficialnew ones (2). The article will attempt to demonstrate that the samepsychological inertia busting benefits may also accrue when the Principles areapplied in a business rather than a purely engineering context.
Set in a business context, the 40 Inventive Principles exhibit a number ofsimilarities and differences relative to their use in technical problem solvingapplications. Probably the biggest difference is that, as yet at least, there isno ‘business’ version of the Contradiction Matrix to help filter the numberof Principles which may be applicable in a given specific circumstance. Thebiggest similarity is that ‘serious’ TRIZ is hard work and this version ofthe 40 Principles, therefore, exists merely to stimulate creative thinking aboutbusiness situations and is not meant to eliminate the need for detailed,in-depth analysis of a particular inventive situation.
To use these 40 Inventive Principles, formulate your problem using the samemethods used for TRIZ for technical problems. It will be particularly helpful toformulate the ideal final result and the reasons that the ideal cannot beachieved. This will usually lead to contradictions. For example, in a customerservice situation, the ideal final result is “The customer gets exactlywhat she needs exactly when she needs it.” The analysis might follow thispath:
“But, I can’t give it to her because my employees don’t have all the knowledge.”
“Because employee turnover is so fast that un-trained employees are used.”
This analysis reveals several potential problems and families of solutions:
The customer gets what she needs without (direct) help of employees.
The employees have the knowledge without training
The trained employees don’t leave the job.
Now use the 40 principles to look for solutions to each of these categoriesof problems, then select the one (or more) that has the highest probability ofworking in this situation. When applying the 40 inventive principles keep inmind the TRIZ concepts of removing the reason for the contradiction, and usingthe available resources.
It is a good idea to use the principles in random order (don’t read the listfrom 1 to 40 each time!) to keep your thinking independent.
Text in green denotes changes made to the wording ofthe original Inventive Principle text in order to better suit business andorganizational terminologies.
Principle 1. Segmentation
A. Divide an object into independent parts.

Principle 3. Local quality
A. Change an object’s structure from uniform to non-uniform, change anexternal environment (or external influence) from uniform to non-uniform.
- Moves away from rigid salary structures/job grading.
- Flexible working hours.
- Franchise fast food outlets have local dishes in addition to normal product range.

Principle 4. Asymmetry
A. Change the shape of an object from symmetrical to asymmetrical.
- (Proportionately) more ‘P’ or more ‘S’ in the Deming PDSA cycle
- Skewed normal distributions.
- Use a different marketing approach for each class of clients. (Combine with Segmentation and Local Quality–make each class smaller to be sure the approach is exactly tailored to it.)
- Budget for different departments individually rather than using a constant percentage increase or reduction for all departments
B. If an object is asymmetrical, change itsdegree of asymmetry.

Principle 7. “Nested Doll”
A. Place one object inside another; place each object, in turn, inside theother.
- Mapping priority innovation areas (Reference 3, pp136-7)
- Four levels of knowledge – 1) Basic Skills, 2) Know How, 3) Process Management, 4) Strategic Vision – contained in effective company (e.g. Sony) training schemes – (Reference 3, pp292-4)

Principle 8. Anti-Weight
A. To compensate for the weight (downward tendency)of an object, merge it with other objects that provide lift.
- In a merger of two companies, one ‘lifts’ the other with whatever its stronger features are (distribution system, marketing, methods, capital, etc)
- Companies increase flagging sales by making connections with other rising products (e.g. movie tie-ins)
- ‘This is my depressed stance. When you’re depressed, it makes a lot of difference how you stand. The worst thing you can do is straighten up and hold your head high because then you’ll start to feel better. If you’re going to get any joy out of being depressed, you’ve got to stand like this.’ Charlie Brown
- “Whenever I feel afraid, I hold my head erect, and whistle a happy tune, and no one will suspect I’m afraid.”–Anna in “The King and I” by Rogers and Hammerstein
B. To compensate for the weight (downward tendency)of an object, make it interact with the environment (e.g. use globallift forces).
- A small company is ‘lifted’ by a resource – use of a transportation network, etc – to the level of the larger companies
- Political parties boost poll ratings by attaching themselves to popular causes
- Attach product/service marketing to customer and business driving forces (Megatrends – aging population, desire for flexibility, simplicity, etc)
Principle 9. Preliminary Anti-Action
A. If it will be necessary to do an action with both harmful and usefuleffects, this action should be replaced with anti-actions to control harmfuleffects.
- When making a public announcement, include all the information, not just the harmful parts (e.g. Johnson & Johnson’s handling of the Tylenol tampering case)
- Use formal risk assessment methods to quantify risk and identify mitigation actions before (and during) a project
- Customer trials/segmented launch of (high risk) new products (e.g. film companies film several endings to a movie and trial with different audiences before finalising selection)
- Use of voluntary redundancy/pay-cuts/short-time working/job-sharing as alternatives to down-sizing
B. Create beforehand stresses in an object that will oppose knownundesirable working stresses later on.

A. In a potential field, limit position changes (e.g. change operatingconditions to eliminate the need to raise or lower objects in a gravity field).
- Make ‘horizontal’ career changes to broaden skills
- Team members distribute their own merit award money (rather than often divisive management dictate)
- Force-Field Analysis – group discussion of the phrase ‘forces push in various directions’ – teambuilding/problem-solving technique discussed in Reference 3.

C. Turn the object (or process) ‘upside down‘.
- Cash-till assistant is the most important part of a retail organisation
- Computer help lines were often originally set up with relatively no-technical staff at the front-end, directing calls to progressively more technically able staff the more complicated the problem is. Latest logic suggests reversing this trend – i.e. place the most qualified staff as first point of contact (e.g. IBM)
- Product- rather than function- based organisation structure
- ‘Ready, Fire, Aim’ – Tom Peters (18)
- Mercedes Benz vision changed from ‘the best or nothing’ to ‘the best for our customers’ – i.e. shift from internal to externally focused vision statement.

B. Divide an object into parts capable of movement relative to each other.
- Work teams oriented to achieve same goal, but work at different rates on different objectives
- Geographically or functionally independent business units
- Conglomerate structures
C. If an object (or process) is rigid or inflexible, make it movable oradaptive.

- Changing the supervisor’s role; avoid ‘whack-a-mole’ firefighting (Reference 10, p20)
- Flexible organisation structure (chaocracy)

- Shift from portrait to landscape report format
D. Use ‘another side’ of a given area.
- View your organisation from the outside – either directly or using consultants, ‘mystery shoppers’, etc.
- New ways of looking at the selling process – instead of selling carpets to its commercial and industrial customers, Interface now offers what it calls the “Evergreen Lease.” Its customers no longer buy carpets or pay an installation fee – they just pay a monthly service fee that guarantees they will always have clean, attractive carpets (22)
- ‘The seeing of objects involves many sources of information beyond those meeting the eye when we look at an object. It generally involves knowledge of the object derived from previous experience, and this experience is not limited to vision but may include the other senses: touch, taste, smell, hearing, and perhaps also temperature or pain.’ R.L.Gregory

Principle 18. Mechanical vibration
A. Cause an object to oscillate or vibrate.
- Use the catchball process of hoshin planning to get the whole organisation ‘vibrating’

- ‘He inspired in us the belief that we were working in a medium that was powerful enough to influence the world’ Lillian Gish on D.W.Griffiths (12)
C. Use an object’s resonant frequency.
- Use strategic planning (policy deployment, hoshin Kanri) to select the right frequency and get the organisation resonating at that frequency to accomplish a breakthrough strategy
- Creating extra-ordinary unity of purpose in a work-team (e.g. Don Petersen’s story of the Ford versus Mazda ‘competition to win the transmission job for the FWD Taurus (23))
- ‘Kansei’ – Japanese term for resonance/one-ness between product and user (Reference 23, pp 139-45)
D. Use piezoelectric vibrators instead of mechanical ones, E. Usecombined ultrasonic and electromagnetic field oscillations. (Useexternal elements to create oscillation/vibration)
- Bring new blood into team
- Hire consultant
Principle 19. Periodic Action
A. Instead of continuous action, use periodic or pulsating actions.
- Batch manufacture.
- Tidal traffic flow schemes ease transport into and out of busy areas

- Make potentially polluting industries place flow intakes downstream of flow outlets on a river
C. Amplify a harmful factor to such a degree that it is no longer harmful.
- The famous software solution ‘that’s not a bug, it’s a feature’
- Benevolent dictatorship (25)
- Reduce resourcing levels to such an extent that new ways of doing the job have to be discovered
- Restrict supply of goods to create scarcity value (e.g. some sports car manufacturers seek to maintain a multiple year waiting list on vehicles)
Principle 23. Feedback

- ‘Open the kimono’ – everything out in the open communication (Reference 14, Chapter 9)
- ‘Supravision’ rather than ‘supervision’
- ‘Co-evolutionary marketing’ – e.g. Amazon.com invites readers to write on-line book reviews; other readers often prefer these views to professional reviewer evaluations, therefore people visit the site more often (26)
- Motorola ‘open dissent’ policy – employees fill in a minority report to senior management when ideas they consider valuable are unsupported by colleagues and immediate superiors (Reference 27, pp164-6)
- Use of ‘half-life’ as a measure of improvement (e.g. time taken to half product development time) to encourage large-scale thinking
Principle 24. ‘Intermediary’
A. Use an intermediary carrier article or intermediary process.
- Use of impartial body during difficult negotiation (e.g. ACAS)

- Franchisee acts as intermediary between corporate vision and customer
- Travel agent (NB can also mean removal of intermediary – e.g. direct selling).

B. Merge one object temporarily with another (which can be easilyremoved).
- Introduction of specialist trouble-shooting or fire-fighting teams
- Hire consultant.
- Use bridging loan arrangements to help cashflow
- Subcontract occasional services – accounts, cleaning, transport, etc.
Principle 25. Self-service
A. Make an object serve itself by performing auxiliary helpful functions
- Quality Circles
- Self-help groups
- Brand image circularity – Harvard Business School produces bright people; these people enhance the School’s reputation; hence lots of people apply; hence they only take on very bright people; bright people in equals bright people out; and so the circle re-enforces itself.
- ‘Cookies’ on the Internet gather data useful for future marketing activities, while performing a useful service for the ‘surfer’
- Bar-codes in supermarkets provide instant pricing information, but the system also gathers information to assist future marketing decisions
- Edward DeBono’s suggestion to Ford UK that they buy National Car Parks and then only let Ford cars into the parking lots – i.e. motorists buying a Ford are also buying a parking place in every city (24)
B. Use waste (or lost) resources, energy, orsubstances.
- Re-hire retired workers for jobs where their experience is needed
- Loan out temporarily under-utilised workers to other organisations (load-capacity balancing across companies – e.g. footballers – win-win situation; the player stays match fit, the loaner saves wages, the loanee fills skill shortage)
- ‘Industrial eco-systems’ (22, 29) – e.g. plan factories so that waste heat from one operation provides power for another operation, install co-generation equipment so that waste heat can generate electricity–use it for your own operations or sell it to the electric power utility.
- ‘Brown-field’ developments
- Body Shop re-cycles used containers brought back by customers – helps promote corporate green image
- Re-cycle all packaging material
- Scan mail into data systems and recycle the paper
Principle 26. Copying
A. Instead of an unavailable, expensive, fragile object, use simpler andinexpensive copies.
- Virtual reality via computer instead of an expensive vacation
- Listen to an audiotape instead of attending a seminar.
- Rapid prototyping (e.g. stereo-lithography)
- Scan rare, historic books, documents, etc so they are accessible to all and the original remains protected
- Lascaux II – reproduction of Lascaux cave paintings which is open to visitors
. Replace an object, or process with optical copies.
- Virtual product service manuals.
- Video-conferencing instead of physical travel
- Use a central electronic database instead of paper records in cases where multiple users would benefit from simultaneous access to data – e.g. medical records, customer data, engineering drawings, etc
- Keep your personal calendar on a web-site so you (and others?) can access it from any computer, and it can’t get lost
C If optical copies are used, move to IR or UV (Usean appropriate out of the ordinary illumination and viewing situation).
- Evaluate employee morale using multiple methods such as interviews and questionnaires (2 different ‘wavelengths’)
- Evaluate customer satisfaction using multiple techniques
- Have your customers benchmark you/have your suppliers benchmark you
Principle 27. Cheap Short-Living Objects
A. Replace an expensive object with a multiple of inexpensive objects,compromising certain qualities (such as service life, for instance).
- Use disposable paper objects to avoid the cost of cleaning and storing durable objects. Plastic cups in motels, disposable diapers, many kinds of medical supplies.
- Numerical simulation – operational analysis (virtual war-gaming, virtual business development, strategic planning modeling).
- Flight simulator reduces pilot training costs.
- Swatch ‘renewed impulse’ buying ‘ – ‘Change clothes? Change Swatch’.
Principle 28 Mechanics Substitution
A. Replace a mechanical means with a sensory (optical, acoustic, taste orsmell) means.
- CEO of budget motel chain; ‘our goal is that when you turn out the lights and climb into bed, you think you are at the Hilton’ (16)
- Have retail customers enter data by means of a touch screen, instead of filling out a form that must be keyed in by employees. (Wedding registries, etc. use this)
- Electronic voting
- Supermarkets pump bakery odours around the store to help advertise bread products
B. Use electric, magnetic and electromagnetic fields to interact with theobject.
- Mrs Fields Cookies has a morning video/internet conference with all franchisees – electronic communication replaces memos, etc.
- Automatic GPS sensors inform central control point where (e.g. delivery trucks or taxis) are
- Electronic tagging
C. Change from static to movable fields, from unstructured fields to thosehaving structure.

- Use a radio transponder payment system for traffic control (Highway 91 in California). The fee ranges from $0.50 to $3.50 depending on how heavy the traffic is on the free part of the highway. Radio signals deduct the payment from the users’ account when the car enters the special traffic lane.
Principle 29. Pneumatics and Hydraulics
A. Use gas and liquid parts of an object instead of solid parts (e.g.inflatable, filled with liquids, air cushion, hydrostatic, hydro-reactive).

- Flexible (fluid) organisation structure versus old fixed hierarchical structures
- Liquidation of assets
- Introduction of ‘breathing spaces’ into contracts
Principle 30. Flexible Shells and Thin Films
A. Use flexible shells and thin films instead of three-dimensionalstructures
- The thinnest film is a single molecule thick. Likewise, the thinnest organisation structure is one employee thick. Get faster customer service by having the single employee customer service agent have all the necessary data easily available, so the customer only deals with the single, flexible ‘shell’ of the organisation not the whole bulky volume.
- Card transactions instead of money – e.g. vending machines in companies use employee ID card and charges are debited direct from salary
- ‘Cardboard police’ – 2D policemen or police cars over freeway bridges used as a means of slowing down traffic
- Inflatable ‘passenger’ for lone drivers out late at night
B. Isolate the object from the external environment using flexible shellsand thin films.
- Office workers in open areas can use flexible curtains to shut themselves off from the visual chaos of the open area when they need to concentrate rather than communicate
- Use ‘trade secret’ methods to separate company proprietary knowledge from general knowledge
- ‘Umbrella’ organisations
- ‘We like to delegate and leave people as free as possible, so we try to push management decisions down the line. We run Rolls-Royce with a very thin corporate structure’, Lord Tombs of Brailes, ex-Chairman of Rolls-Royce (32)
Principle 31. Porous Materials
A. Make an object porous or add porous elements (inserts, coatings, etc.).
- Think of the customer-facing layers of a company as a porous membrane which filters information flow both into and out of the organisation
- Improve internal communications by creating Intranet accessible by all hierarchical layers; giving workers access to CEO and vice-versa.
- ‘Trickle-down’ economics
- Government ‘leaks’ – used as a way of gauging public reaction to (usually) controversial issues
B. If an object is already porous, use the pores to introduce a usefulsubstance or function.
- Empower the customer facing layer (information is the thing that fills the pores – see 30A).
- Use mind-maps (30), self-patterning capabilities (21), etc to improve the information/knowledge intake and filtering abilities of the brain
- Media relations department turns spin-doctor and/or marketing feedback gatherer

A. Change the color of an object or its external environment.
- Red/Blue proposal preparation teams
- Use of lighting effects to change mood in a room or office
- Six Thinking Hats (33)

- Highlighter pens
B. Change the transparency of an object or its external environment.
- ‘Transparent’ organisations
- Transparent communications
- Importance of creating clear, concise mission statement (34)
- Smoke-screen/mis-information to disguise confidential R&D etc activities
Principle 33. Homogeneity
A. Make objects interact with a given object of the same material (ormaterial with identical properties).
- Co-located project teams
- Internal customers
- Product branding/product families
- Boeing ‘Working Together Teams’ – bring customers and suppliers into design loop.
- ‘Constancy of Purpose’ (Point No. 1 of Deming’s Fourteen Points (5))
- ‘Singing from the same hymn sheet’
- Common data transfer protocols between different organisations
- ‘The best way to make a silk purse from a sow’s ear is to begin with a silk sow. The same is true of money’ (Augustine’s Law #1 (Reference 8))
Principle 34. Discarding and Recovering
A. Make portions of an object that have fulfilled their functions go away(discard by dissolving, evaporating, etc.) or modify them directly duringoperation.
- Flexible, variable-sized project teams
- Load/capacity balance using contract labour
- Contract hire of specialised equipment/facilities, etc
B. Conversely, restore consumable parts of an object directly in operation.
- Need to periodically re-energise continuous improvement initiatives (‘enthusiasm injections’)
- Life-long learning (where individuals are given responsibility for managing their own personal continuing education, ensuring skills remain up to date)
- ‘In a start-up company, you basically throw out all assumptions every three weeks.’ Scott McNealy
Principle 35. Parameter Changes
A. Change an object’s physical state (e.g. to a gas, liquid, or solid).
- Virtual prototyping
- Numerical simulation
- Virtual shopping – e.g. Amazon.com
- Telephone banking
- Electronic voting in elections
B. Change the concentration or consistency.
- ‘Six Thinking Hats’ (33)
- ‘Six Action Shoes’ (35)
- Change the team structure (e.g. football teams use substitutes)

C. Change the degree of flexibility.
- Introduce intelligence into on-line catalogues (e.g. first generation catalogues were replicas of previous paper versions, latest generation incorporate search engines, expert systems, etc)
- Software with options for ‘beginner’ through to ‘expert’ usage
- Moves away from fixed clothing size partitions – e.g. ‘Personal Pairs’ – a customer at a participating store chooses which fabric he/she wants, then is measured. Those measurements are transmitted instantly to a Levi’s plant in Tennessee where the data controls a laser cutter. The bar-coded pieces are stitched on the regular assembly line, and mailed directly to the customer. (The custom Levi’s, which customers love, run about $15 more than off-the-rack ones) (22)
D. Change the temperature.
- Get customers excited (‘hot’) about the product by giving them ownership of the change
- Get employees excited about the future of the company by using full involvement strategic planning, or stock options, or… etc.
- ‘A fired-up team wins games even if it’s not the best team. A fired-up company can achieve the same result’ (34)
Principle 36. Phase Transitions
A. Use phenomena occurring during phase transitions. (Awarenessof macro-scale business phenomena)
- Awareness of the requirements of different stages – conception, birth, development, maturity, retirement – of a project (e.g. shifting manpower requirements, shifting budget requirements).
- Transition from a ‘bull’ to a ‘bear’ market.
- Tendency to relax after receiving a Quality Award, Innovation Award, etc.
- Forming/storming/norming/performing phases of team development – e.g. take advantage of enthusiasm dip during storming-norming (3)
Principle 37. Thermal Expansion
A. Use thermal expansion (or contraction) of materials.
- If employees are excited (‘hot’) each can do more in the space that expands to exist between them.
- ‘A fired-up, empowered, appreciated individual will do the work of three who aren’t’ Anon.
- ‘It seems safe to say that significant discovery, really creative thinking, does not occur with regard to problems about which the thinker is lukewarm’. Mary Henle
B. If thermal expansion is being used, use multiple materials withdifferent coefficients of thermal expansion.
- Expand or contract marketing efforts depending on the product’s ‘hotness’ – rate of sales and profitability

- Consider personal chemistry issues when assembling a project team – find people who will spark-off interesting reactions with each other.
- Deming’s 4 stages of learning – unconscious incompetence, conscious incompetence, conscious competence, unconscious competence
- Focus teams on a single project only (give them an enriched environment full of success factors
- ‘Leadership is a potent combination of strategy and character. But if you must be without one, be without strategy.’ General H. Norman, Schwartzkopff (17)

- Corporate Jester
- ‘Devil’s Advocate’
- ‘I like Bartok and Stravinsky. It’s a discordant sound and there are discordant sounds inside a company. As president you must orchestrate the discordant sounds into a kind of harmony. But you never want too much harmony. One must cultivate a taste for finding harmony within discord or you will drift away from the forces that keep a company alive’ Takeo Fujisawa, Honda co-founder.
Principle 39. Inert Atmosphere
A. Replace a normal environment with an inert one.
- Moves away from the (normal) disruptive performance appraisal, merit award, and reward environment to an (emotionally neutral) more fair system of working practice (36, 37).
