“…The TRIZ innovation methodology can be useful when confronted with any contradiction or problem by providing a systematic way to explore a solution space. Applied to trade studies, TRIZ can result in more robust compromise solutions [1]. As has been shown by engineers in many companies, including SC Johnson, Proctor and Gamble, Motorola, Hewlett Packard, GE, Unilever, and Dow Chemical, application of TRIZ principles to problem spaces results in a more effective solution [2,15,16,42].…”

“…The systems engineer is responsible for developing design ideas, comparing options, resolving conflicts, and optimizing the performance of the system. Systems engineers have long utilized their diverse backgrounds and skills to harness innovations based on connections [1,2]. There are few ways to systematically explore these mental connections which are where innovation is usually found, and this lack of systemization makes innovative ideas seem like the result of chance or inspiration.…”

“…It clearly applies to the physicality of a digital system (hardware), but its application to the intangible world of bits and bytes (software and data) is not so clear. Analogies of the principles to the world of software have been proposed [18][19][20][21][22] and attempts have been made to integrate the concepts of TRIZ into systems engineering tools and processes [1,23,24]. Concluding that the "39 constraints were not applicable" [2] in their use of TRIZ to innovate IT solutions has called the contradiction matrix into question.…”

While innovation from the systems engineer is desirable at every step in all phases of systems engineering, there must be a methodology to evaluate alternatives. A formal methodology, complete with verification and validation of the results, was developed in 1946 by Soviet engineer Genrikh Saulovich Altshuller and is known as "The theory of inventor's problem solving", or TRIZ. This approach improves the way a systems engineer's thinking progresses about a problem's solution from "what is" towards "what will be" in the innovative development of a solution. The original distinguishing features of systems used in TRIZ were derived from innovations addressing physical, mechanical system, and few of them apply to digital systems. This paper presents additional characteristics that should be considered in the Reduction phase when applying TRIZ to innovation in digital systems engineering and a redefinition of the principles. With the additions of these distinguishing features for digital systems, TRIZ will become an invaluable tool for the digital systems engineer. Systems 2019, 7, 39 2 of 23with the "what is" of the problem space and move towards the "what will be" of the solution space [5]. Application of the TRIZ methodology provides the bridge between these two; it is the problem space which is characterized and resolved. TRIZ has the reputation as the only systematic problem solving and innovation tool-kit available [6].The TRIZ tool-kit is comprised of several tools. Each is most effective when applied against a particular type of problem [6] but they can all be used in conjunction with each other. The tools that comprise this methodology include inventive principles, evolution laws, smart little people, ideality, substance-field analysis, flow analysis, feature transfer, standard solutions, separation principles, multiscreen (9-windows), trimming, and contradictions. This work focuses on the tool that used most often: contradictions. This process is very powerful for breaking out of existing design paradigms and entering into new and exciting ones [7].TRIZ can be considered as a set of all methods necessary for solving an inventive problem from the beginning to the end, and many approaches have been developed combining TRIZ with other methods: Design for Six Sigma (DFSS) [7,8]; the philosophies of Robust Design [9] and Quality Function Deployment [10,11]; Suh's Axiomatic Design [12]; Design Structure Matrices [13]; and Synectics [14]. Recently, a study was made of over 200 case studies where TRIZ had been used throughout industry [15]. TRIZ has become a powerful tool in the industrial world, helping companies innovate solutions their customers have not yet specified. At Samsung, for example, "TRIZ is now an obligatory skill set if you want to advance within Samsung" [16].The generic solution triggers resulting from TRIZ help structure problems and suggest directions for specific solutions. It is important to note that there exists a considerable gap between the generic solution triggers which have been develope...

“…Bryan and Dagli (2005) focused on applying TRIZ for knowledge capture. Also, the TRIZ Trade study tool was developed by Blackburn, Mazzuchi, and Sarkani (2015) to identify system conflicts, both across alternatives and within a technology. The resulting tool also compares options and aims to optimize how systems work at different stages of decomposition.…”

An SSM‐TRIZ Methodology for Business Problem Structuring

Checkland developed Soft Systems Methodology (SSM) to address problem situations from a systems perspective; however, SSM needs to be extended with other methods to find superior solutions that overcome the need for a compromise or trade‐off between conflicting or contradictory elements. This paper extends Checkland's SSM approach to resolve problems with conflicting or contradictory elements. This work integrates the powerful benefits of TRIZ‐based analysis into SSM and provides a means for systemic resolution of business problems with conflicting sub‐system elements. This paper acknowledges that soft problems can have conflicting relationships among their elements, compares the strengths and weaknesses of SSM and TRIZ in problem structuring, and presents a collaborative SSM‐TRIZ approach for problem structuring. Finally, this paper applies the joint methodology to examine the business problem of developing a Professional Development platform for INCOSE. Although SSM‐TRIZ helps structure problems with opposing requirements, it does not always provide definitive, prescriptive solution implementations for technical and business issues. Hence, hard thinking approaches cannot be discarded in practice after implementing SSM‐TRIZ.

“…For example in the article An integration of TRIZ and the systematic approach of Pahl and Beitz for innovative conceptual design process, an integration of TRIZ and conceptual design process was proposed to overcome important deficiencies of conceptual design [6]. There are also some new ideas proposed in Using TRIZ with Other Tools [7] and [15][16].TRIZ theory is used in some other research field, look at the references [1], [8][9] and [11].…”
