Economic development and success depends on defining customer / supplier relationships based on customer needs. This series outlines a method for the service supplier to increase coordination of its actual solutions to customer expectations. This is achieved by combining complementary Theory of Inventive Problem Solving (TRIZ) tools. Including perception mapping (PMap) and action preventing action (APA) a tool developed by the authors to define customer needs.

Often, the problem formulated by the customer is resisted indirectly by a hidden network of problems derived from needs that the customer is not aware of. Analysis of the main customer's needs helps formulate the problem correctly prior to solving it. Perception mapping provides hierarchical relationships with different customer inputs such as "what they think / feel," to help identify and eliminate the hidden problems or blockers. Whereas, action preventing action is based on direct observations such as "what they do."

Action preventing action offers a fundamental premise by preventing undesired customer activity. It enables a supplier to reach the highest level of customer satisfaction such as the: "customer does not want to do what he / she is currently doing." Eliminating blockers enables the ability to fit solutions to actual problems and effectively satisfies the main requirements of the customer. This series aims to initiate development of TRIZ methodology for deployment and sustainability within high volume manufacturing corporations. It will also share the authors' approach on possible definitions of TRIZ customer needs. The following is Part Three of the three-part series. Part One discussed customer needs and the evolution of TRIZ methods. Part Two explored perception mapping as a tool for corporate needs analysis and the action preventing action tool for customer needs definition.

Case Study

The management team of an international company producing and supplying Indian food worldwide decided to increase revenue. A long production and delivery cycle was defined as the main challenge to achieve the goal. Management decided to invest in production and delivery cycle time improvements.

They invited a TRIZ expert to define the best way to reduce cycle time. The expert recommended (prior to building a functional model and proposing solutions) a perception mapping (PMap) analysis to examine the broader picture of revenue increase and to identify possible blockers for the changes. The analysis will display the main needs of the production to ensure effectiveness of the cycle time reduction or other directions.

The TRIZ expert said: "What is required in order to achieve higher revenue?" Perceptions were collected and treated by perception mapping. The perceptions matrix is illustrated in Table 1.

Table 1: Perceptions Matrix Case Study
Perceptions	Subject-Action-Object	Assignments	Leads To	Contradictions
Increase salary to avoid leaving of experienced staff	Salary – keeps – staff	A	K	C1
Automation and optimization of charts control	Models – keep – automation	B	D

Link sales data to operation	Automation – keeps – production	D	B

The map shows that the system of Indian food production and delivery is complex with a collector, loops and contradictions. For example, the perceptions "reduce cost" and "increase salary" are both effective, but form a conflicting pair and also form a conflicting chain for the conflicting perceptions. Appropriate methods are needed to resolve such complicated structures. The ranking of the perceptions is shown in Table 2.

It is important to mention that low blocking rank of a perception does not mean it has low importance. To reduce cycle time is an extremely important goal and should be implemented. The management team determined that reducing cycle time would be the most effective way for revenue increase. Nevertheless, the effectiveness of the direct cycle time reduction would be resisted or even blocked by other issues referring to the perceptions receiving higher rank. This means that in order to ensure effective improvement of the revenue by reducing cycle time, the high blocking rank perceptions should be addressed when creating the roadmap of the cycle time reduction implementation.

Figure 1: Perception Mapping Case Study

What are the main results for perception mapping analysis that can be performed by a TRIZ specialist? As shown in the ranking matrix in Table 2, four perceptions received the highest, relatively similar rank:

1. Instructions should be done upon request.
2. Improve learning process.
3. Allow time for individual learning.
4. More focus on the importance of an individual.

All perceptions relate to the same root cause indicating that the company should improve teaching and training processes as a first priority. Successful training would enable successful implementation of the cycle time reduction policy.

Table 2: Perceptions Matrix Case Study Rankings
Perceptions	Assignments	Loops	Connectors	Contradictions	Sum	Blocking Rank
Instructions should be done upon request	O	4	1	3	8	High
Improve knowledge (improve teaching process)	M	4	1	3	8	High

Action preventing action analysis was applied to define real needs based on current activity. The query: "What keeps you busy now?" was dispatched among employees. The answers were analyzed and grouped according to the specific field of operation (FOO). The results are illustrated in Figure 2.

Figure 2: Case Study Share of the Business According to a Different Field of Operation

A relatively low share of occupation with the field of safety indicates that the company has no problem with safety. It seems like the company has already invested enough attention and money into training and special equipment to avoid safety events.

More than 30 percent of the respondents mentioned that they are busy with process control. This indicates that the process control is not developed enough and should be improved. Based on the action preventing action approach the company should implement changes allowing significant reduction or even prevention of any human actions related to process control.

All responses to the question: "What keeps you busy?" were tabulated and treated by the action preventing action method. For each action, action preventing action and general needs were described. Examples are shown in Table 3.

Table 3: Action Preventing Action Analysis Case Study
Actions	Action Preventing Action (APA)	Needs
Inspect recipes	Computerized checker	Automation
Writing instructions	Computerized templates	Automation
Repairing equipment	Equipment failing prediction	Problem solving awareness
Writing e-mails	Templates with automatic dispatch	Automation
Cost reduction projects	Implement Lean	Lean awareness
Learning processes	Arrange permanent seminars for knowlege exchange	Process awareness
Looking for better suppliers	Make suppliers look for your company	Problem solving awareness
Looking for new customers	Make customers look for your company	Problem solving awareness

Summarized results were grouped into generalized needs. The breakdown of the main needs are shown in Figure 3.

Figure 3: Case Study for Main Needs Breakdown Defined from Action Preventing Action Analysis

As displayed through the action preventing action analysis the company has three important needs:

1. Automation
2. Problem solving awareness
3. Process awareness

Satisfaction of the needs will ensure further successful development of the company. The first and most important thing the company needs, however, is automation. This result is in good correspondence with results received from perception mapping (since development of the production and delivery of automation will ensure better conditions for individual development and an increase of their contribution to the company's success).

Conclusion

The three-part series summarized the investigation of customer needs as an important step in ensuring a fruitful relationship between customer and supplier. Perception mapping and action preventing action are powerful tools for the definition of the real needs.

The definition of real customer needs helps with TRIZ methodology implementation and proliferation within large companies.
