Abstract:(1) Catalogs of TRIZ-related Websites in the World have been developed by avolunteer-based international project WTSP.
(2) The Catalogs are now available publicly without charge both for interactive
use at the WTSP site and for downloading, printing, and interactive use atuser's PC.
(3) The Catalogs cover various websites in the fields of TRIZ (including
modernized TRIZ) and around-TRIZ more widely (i.e., creative problem solving
in general, including quality/value/project management, IP, etc.).
(4) Various websites dedicated for the roles of information sending, research,development, promotion, publishing, etc. of such TRIZ-related methodologies
are collected.
(5) Websites are found more useful as units of information resources than(smaller) webpages, papers, patents, etc. and (larger) journals, conferences,
books, etc., because they are kept updated for many years withunity/quality/scope of information by some group or organization, in openly
accessible forms.
(continue)

Abstract (continued):(6) Individual websites are introduced briefly by surveyors/recommenders, andin one-page standard form and (optionally) much longer by the website owners.
(7) Websites are evaluated in respect to their
quality/usefulness/attractiveness/accessibility/scopes/etc. and shownin 5 grades (◎○□ for world level, △ for country level, and －）.
(8) Current World WTSP Catalogs (Beta Edition) list 23 ◎ and 39 ○ websites
in TRIZ while 33 ◎ and 127 ○ websites around TRIZ.
(9) We are working further to make our WTSP Catalogs more useful andattractive for users as well as professionals by voluntary cooperation of manycolleagues in the world.

[1] Introduction: Purposes/Aims and Basic Strategy[1A] Purposes and Aims
Everybody wants to solve various (often difficult) problems in our jobs and daily
lives smoothly and creatively.
There are many methods/references/activities for creative problem solving,
we are told. But they are often not easy to find/access/understand.
Internet keyword searches, for example, give us messy outputs.
For overcoming the difficulty, we organized a voluntary project WTSP (World
TRIZ-related Sites Project) in Dec. 2017.
It aims at building Catalogs of good websites in the world in the fields of
TRIZ and Around-TRIZ (i.e., creative problem-solving methodologies in general).
We started this project in the TRIZ community, but we want to learn/use manyother methodologies for ourselves and suppose people familiar in othermethodologies also want to learn/use TRIZ. Thus, we build our Catalogs
having two pillars, TRIZ and Around-TRIZ.

[1B] Basic Strategies
Websites are meaningful units of information resources;

better than (smaller) webpages, papers, patents, etc. and(larger) journals, conferences, books, etc.
Contents of Websites are kept updated by a group of people for many years
with certain level of unity/quality/scope and include many links totheir original/individual references and to various relevant information sources.
Any Catalog must meet 3 Basic Requirements from Users:(Cf. 'Catalogs of Good Restaurants', 'Catalogs of Sight-seeing Places', etc.)
Req. 1: Collect good items (i.e. websites) widely, select them with evaluation,and show them in categories.
Req. 2: Individual items should be introduced in a proper/fair manner
briefly or closely and guide the readers/users to good items.
Req. 3: It should be easy for users to find one or many items whichmatch their current interest/needs inside the Catalog.
We have designed and tried to build our Catalogs to fulfill all these well.
We have chosen to carry out this project on a voluntary basis, hoping collaboration
by many TRIZ people. Nakagawa is the proposer and Project Leader, and five
TRIZ leaders are invited to be Global Co-editors.

[2] Activities for Building WTSP Catalogs[2A] Activities for Building WTSP Catalogs: TRIZ Sites
WTSP project was supported initially by many TRIZ colleagues;
the Project got about 80 Members from 30 countries (Sept. 2018 at ETRIA TFC).
As a pilot project, Japan WTSP Catalogs (of 92 websites) were made. (Apr. 2018)
Internet surveys of TRIZ sites In the world and in USA were made by Nakagawa(Mar. 2019)

Catalog manuscripts were contributed by TRIZ leaders in Malaysia, China, andRussian Language region. (Jun. 2019).
World WTSP Catalogs of TRIZ Sites were built quickly (Preliminary Edition)
for visualizing our vision (Jun. 2019),
and they were revised into Beta Edition (Jun. 2020)
Many (30 to 40) countries have not contributed their lists of TRIZ sites yet.
USA, UK, France, Germany, Italy, Korea, Taiwan, ....
Recently, Internet surveys of TRIZ sites were made individually in 52 countries(Nakagawa, May - Nov. 2021). -- But not incorporated yet in the World Catalogs.

[2B] Activities for Building WTSP Catalogs: Around-TRIZ Sites
Internet surveys of Around-TRIZ sites In the world were made (Nakagawa,May -Sept. 2019)
Keywords used:
Creative Think Method(Creative / innovative / Systematic) Problem Solve (Method / Process / Technique)Innovation (Process / Strategy / Method / management / Technology)(Quality / Value / Cost / Productivity) (Deploy / Engineering / Management /Control / Analysis) (Method / Technique / Theory / Process / "Case Study")(Patent / IP / "Intellectual Property") (Analysis / Protect / Circumvent / Mapping /Strategy)

About 1000 websites were detected.
Visiting all the sites one by one, he described brief introduction (in 3-15 lines)
and evaluated them tentatively.
The results were made into Preliminary Edition (Jun. 2019) andBeta Edition (Jun. 2020) of the World WTSP Catalogs of Around-TRIZ Sites.

[2C] Evaluation of Websites(Internet surveys output information of hundreds of sites.
-- But messy with noise and difficult to find real good ones. )We should evaluate every site even tentatively and select good ones
for our Catalogs.
Evaluation need to be refined later, probably by public reviews.

Multiple Criteria we use:

Quality (reliable, correct, novel, original, comprehensive, up-to-date, ...)
Usefulness (resourceful, reference, handy, practical, ...)
Attractiveness (interesting, easy-to-understand, illustrative, ...)
Accessibility (open access, free/low charge, used by many, ...)
Scope (scope of the theme/field, scope of activities, ...)

Grading into 5 Levels, showing with the following symbol marks.
◎ Most important (about top 30) in World Catalogs○ Important (about top 100) in World Catalogs□ Worthy in World Catalogs,△ Worthy in Country Catalogs,－ Insignificant / irrelevant.

Roles: (g3) Knowledge sharing

About (Excerpt): Wikipedia is a multilingual, web-based, free-content
encyclopedia project supported by the Wikimedia Foundation and based on amodel of openly editable content. ...
Wikipedia is written collaboratively by largely anonymous volunteers who write
without pay. Anyone with Internet access can write and make changes to
Wikipedia articles. ....
Since its creation on January 15, 2001, Wikipedia has grown rapidly into one of
the largest reference websites, attracting 374 million unique visitors monthly as of
September 2015. There are about 72,000 active contributors working on morethan 48,000,000 articles in 302 languages. As of today, there are 5,937,320
articles in English.
Note (TN, Sept. 26, 2019): Many keywords/terms of our interest in TRIZ andrelated methodologies are explained in Wikipedia. Contents and quality ofthem seem to vary much depending on the items and on languages.
Wikipedia is often used as handy and reliable references by many people
especially on the topics out of one's specialty. Thus the quality of description ofeach item should be important for better introduction of the items for common
people.

[5] Concluding Remarks[5A] User's Evaluation(Dr. Bill Fowlkes, Oct. 2019)

To the World TRIZ-related Sites Project (WTSP) Global Co-editors:
I welcome the work you are doing to collect, organize, describe and link tothe many internet sites that are of interest to students and practitioners ofinnovative methods such as TRIZ.
I have created a new bookmark folder with links to the WTSP Catalogs of
TRIZ sites and the WTSP Catalogs of AROUND-TRIZ sites, and I expectthat I will be referring to them frequently.
The aggregation of these sites is much better than trying to find the datawith a Google search, because the information is curated and brief
descriptions are provided.
I encourage TRIZ providers and other content creators working in TRIZ
related fields to participate in this project and make the World TRIZrelated Sites Project the best it can possibly be.

[5B] WTSP Project: Aims (Oct. 2018) Revisited・ To build Catalogs of TRIZ-related Sites- of each country (in their own language, then in English) and- of the whole world (in English, then in many languages)- with appropriate (brief but close) introduction of individual sites- with appropriate selection of (useful and important) sites- for various people (unfamiliar, beginners, users, and experts in TRIZ)- in the field of TRIZ and relevant methodologies- as reliable sources of information (on theories, applications, activities)
・ To keep the Catalogs up-to-date- accepting new and revised information regularly- revising all the Catalogs every two years
・ For promoting TRIZ and relevant methodologies further in the world
・ By voluntary collaboration of many TRIZ colleagues in the world
We have come half the way, having built the Beta Edition of World WTSP Catalogs.

[5C] For Further Enhancement of the World WTSP Catalogs:
To Users/experts of TRIZ and relevant fields:
Please use and learn with the WTSP Catalogs:
WTSP Catalogs are rich and handy to access the whole TRIZ information.
WTSP Catalogs may be used freely at out WTSP website.
http://www.Osaka-gu.ac.jp/php/Nakagawa/TRIZ/eTRIZ/eWTSP/

You may download the PDF file of WTSP Catalogs for Print, print it,
ａｎｄ use it interactively on your PC as if working at the WTSP site.
WTSP Catalogs for Print are accessible at several other websites.
To website owners:
Please write an introduction of your site in our Standard Form (A4 1 page).
Send it to TRIZ leader(s) in your country and to WTSP Project Leader.
Many users/experts will visit your websites.
To TRIZ leaders or voluntary coordinators (in each country/specific field):
Please list up recommendable websites (in your country/specific field).
Please encourage the site owners to write their site introductions.
Please coordinate the people in your country, and send the manuscript ofyour country's WTSP Catalogs to the WTSP Project Leader.
Let's work Together! Connected!! Make our Catalogs Attractive& Useful!!!
