I wish I had learned to disagree politely, convincingly, and respectfully. The trick is listening and really understanding the "opposite" view

Get accepted into YC S19! My co-founder and I weren't accepted to the W19 batch but we learned a lot from SUS and are continuing to build product and talk to users.
lispytriz | 7 years ago | on: TRIZ, a problem-solving, analysis and forecasting tool
Hi! I'm really happy to see TRIZ mentioned here on HN. I consider myself a TRIZ geek and GS Altshuller, the "father of TRIZ" was one of my influences growing up.
The 40 Principles are rarely used nowadays for solving complex problems. They were originally used in the 1960s to catalog the solutions to "standard" tradeoffs. Eventually, GSA and the rest of the TRIZ community realized that it was more effective to analyze the root of the tradeoff, and solve the problem there.
For those who are interested, I can list down some of the TRIZ tools worth learning. My co-founder and I are applying for the S19 batch and have used some of these tools to understand problems and clarify our ideas.
TRIZ tools are split into two (pre-1985, called Classical TRIZ, and post-1985, called Modern TRIZ)
By general consensus, the most powerful tools in the Classical TRIZ toolkit are: 1. ARIZ 85c (the "crown jewel" of Classical TRIZ) 2. Substance-Field Analysis (akin to the contradiction matrix) 3. 76 Inventive Standards (akin to the 40 inventive principles)
In my opinion, the most powerful tools in the Modern TRIZ toolkit are: 1. Root Conflict Analysis (like Root Cause Analysis but designed to find tradeoffs and roots of the tradeoffs; can also be used for software architecture problems) 2. Advanced Function Analysis (component-interaction analysis with spacetime-correction)
There's a nice article of the overview of the chronological order of TRIZ tool development written by Valeri Souchkov, designer of Root Conflict Analysis.

This is a crowdfunding site built in Bubble that lists charities to which one can make tax-deductible donations.
Our goal is to help high-impact nonprofits fundraise from prospective donors with the fiscal incentive to make recurring donations.
Would deeply appreciate feedback on this product, your relevant experience in making tax-deductible donations, and pointers to nonprofits and projects you believe should be fundraised for especially in this current pandemic.
