We started the World TRIZ Sites Project (WTSP) in Dec. 2017 for the purpose of building catalogs of TRIZ-related Web sites in the World. Getting support by a number of TRZ colleagues, we started the project to achieve by voluntary cooperation of many (hopefully about 100) TRIZ colleagues coming from various countries. Our basic strategy was to build Country WTSP Catalogs in each country first and then build World WTSP Catalogs by using selected sites. Japan WTSP Catalog was made and posted in English in Apr. 2018 as an example. Internet surveys of TRIZ sites located in each country were shown for 33+ countries. Adding new members at TFC2018, we got over 70 voluntary members from 30+ countries. But the actual WTSP work in individual countries is proceeding only slowly till recently. So we started Top-down approaches using Internet surveys in global scale, for TRIZ sites written in several major languages, and for sites around TRIZ by using different keywords in wider scopes. We also realized the importance of showing concrete images of our World WTSP Catalogs and practical processes for achieving it. Thus we proposed an ‘Ideal image’ in the form of WTSP Database System and turned it into a simple and feasible structure. Our World WTSP Catalogs is made as a small Web site, which has ‘Table of sites’ (or Index) page(s) and many ‘Descriptions of sites’ pages, where many hyperlinks flexibly connect individual sites from the Index to the Description. Japan WTSP Catalog (for people in Japan) was rebuilt into World WTSP Catalog (Japan Part) (for people in the world). Practical Guide for Teams to build the World WTSP Catalogs is shown with templates and easy processes based on a new strategy “to list up and describe highly recommendable sites only in each country and to build the World WTSP Catalogs as soon as possible”.We are going to report the draft version of World WTSP Catalogs at TFC2019. Getting Country Editors in every country is the crucial issue.
