MPUF (Microsoft Users Forum) is a NPO aiming at improvement in the quality of Project Management. The number of study groups is launched in about 20, the USIT/TRIZ study group was launched in April,2007.. Members aim at improvement through an event, a seminar, a community, a study group, about various subjects related to project management,The theme introduced this time the achieved result through Working Group activity of a study group.
The following result was able to be achieved by using the technique of USIT in WG to achieve the problem where the paper fastener held the current state.
1. It became easy for the procedure and the thing that had to be done to become clear by using the USIT workbook (Announced from this society last year) and to advance the discussion. And, the USIT template form is used to arrange the result. As a result, it was confirmed for the summary of passage by each STEP of USIT to able to attempt both sharing the result effectively.
2. KeyWord of a wide viewpoint is obtained from this approach, and it introduces the idea of shoes that appear from the KeyWord.
Extended Abstract
In the USIT workbook"Purpose", "Note", "Work procedure", and "Notice point" of each item are first described, and the next case example is described . In actual work we will start by seeing it , the work that we have to do becomes clear. and It came to be able to confirm STEP of work by using USIT template form's

In the initial half of the Authors' Abstract, the nature and aim of the group is explained as follows:
MPUF (Microsoft Users Forum) is an NPO aiming at the improvement in the quality of Project Management. The number of study groups launched is about 20, and the USIT/TRIZ study group was launched in April, 2007. Members aim at improving through events, seminars, communities and study groups, about various subjects related to project management. The theme introduced this time is the achieved result through the Working Group activity of the study group.
[*** About the MPUF USIT/TRIZ Study Group, please refer to my explanation in the review of Oral presentation by its another subgroup, H. Kosha et al.
The following result was able to be achieved by using the technique of USIT in the WG to cope with the issues facing the existing paper fasteners.
1. It became easier to advance discussion because the procedure and things to be done become clear by using the USIT workbook (announced from this society last year). And, the USIT template form was used to arrange the results. As a result, it was confirmed that the results could be effectively shared by using the USIT template form to summarize the process of each STEP.
2. Key Words of a wide viewpoint were obtained from this approach, and some ideas generated from these Key Words will be introduced.
As described in the Authors' Abstract, one of the aims of their present work was to follow the steps of the "USIT Workbook" developed in the Study Group and reported a year before by Takuo Maeda et al. The Authors presented their results in detail with 32 slides following the steps. The slide (right), for example, is the description they wrote in the Workbook at the sub-stage [1-(2): Figure of problem situation] in the stage: 1. Problem Definition. The problem was to improve the paper fastener for easier/faster replacement of the papers. To clarify the problem, the slide illustrates the whole process of handling the paper fastener for deleting/inserting several pages. The main difficulty of the process lies at the step (S4) of passing the fingernails through the holes of many pages. |
 |
The USIT Process (in this Workbook) has 6 stages: The slide (right) shows the initial steps of the Particles Method. Problem situation and corresponding ideal image are sketched, and then the Particles (i.e., imaginary magical substance or Field) are shown with Star marks at the places where the two sketches are different. We imagine that the Particles have some magical capability of achieving the ideal results, and try to understand how they could achieve them. |
 |
The slide (right) shows the latter half of the stage of the Particles Method. Now the Authors construct the Action & Property Diagram (or "AND/OR Tree" according to Sickafus' original naming). The ideal (or most desirable) solution to be achieve is written at the top of the tree diagram. Then desirable partial solutions (which the Particles can achieve in a magical manner) are written step by step downward in the tree structure. The lower branches need to be combined with either AND or OR relationship to achieve the upper node. In the bottom half of the Action& Property Diagram, desirable possible properties are listed up. By using this method the Authors have obtained various suggestions to ideas/solutions. |
 |
USIT has a system of Operators for generating solution ideas. The main 5 USIT Operators are: Pluralizing Objects, Dimensional Change in Attributes, Redistribution of Functions, Generalization of Solutions, and Combination of Solutions. They contain 32 sub-operators in total. The slide (right) shows a summary of ideas which are generated in the analysis stages and in the solution generation stage by using various USIT Operators. They are classified here in terms of their intentions. The Authors have generated a large number of ideas.
|
 |
Then the Authors have tried to combine various ideas into feasible solution concepts. The following 4 slides demonstrate how the ideas are combined into solution concepts.
The Authors gives their summary as shown in the slide (right). They have demonstrated the whole process of USIT along their "USIT Workbook" as the template. Since they used a familiar item, a Paper Fastener, the Authors' presentation is easy to follow and good as a case study. They have generated many ideas and their way of thinking can be traced in the presentation. In this sense, the "USIT Workbook" has been shown effective. [*** Even though the Authors have generated many ideas and demonstrated four solution concepts, I am not satisfied in the effectiveness and feasibility of their solution concepts. In the USIT/TRIZ Study Group I suggested them that the main difficulty in using the current Paper Fastener is arranging/keeping many pages of paper in a neatly-stacked position in the process of passing the two fingernails through the paper holes. Thus my suggestion was to make a complementary device for arranging and keeping the pages in a neatly-stacked way and to use some cloth-like material with "magic tapes" at the ends for fastening them together.] |
