Good, fast, cheap – editable iron triangle
If you ever needed to visualise the 3 things that you can’t have all at once, like GOOD, FAST, CHEAP, I made a little tool for you! You can use it whenever you are having a project deadline discussion at work or just for fun. Enjoy.
Good, fast, cheap – editable iron triangle launched on April 12, 2023 with 28 votes, #1,508 of 4,853 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
This tool visualizes the classic project management trade-off between quality, speed, and cost—the iron triangle concept that suggests you cannot optimize all three simultaneously. Users can adjust the balance between good, fast, and cheap to illustrate why project compromises are necessary. It's designed for workplace discussions about deadlines and resource allocation, or simply as an educational demonstration of this fundamental constraint.

From the sources
Good Fast Cheap is a project management principle known as the Project Management Triangle or Iron Triangle. The idea behind this principle is that you can only achieve two of the three factors: good, fast, and cheap. This editable version allows you to change the values and modify it to your needs.

FastGraphRAG – Better RAG using good old PageRank2024 · github.com · ▲457Hey there HN! We’re Antonio, Luca, and Yuhang, and we’re excited to introduce Fast GraphRAG, an open-source RAG approach that leverages knowledge graphs and the 25 years old PageRank for better information retrieval and reasoning. Building a good RAG pipeline these days takes a lot of manual optimizations. Most engineers intuitively start from naive RAG: throw everything in a vector database and hope that semantic search is powerful enough. This can work for use cases where accuracy isn’t too important and hallucinations are tolerable, but it doesn’t work for more difficult queries that…
Weave2025 · app.workweave.ai · ▲237Hey HN, We’re building Weave: an ML-powered tool to measure engineering output, that actually understands engineering output! Why? Here’s the thing: almost every eng leader already measures output - either openly or behind closed doors. But they rely on metrics like lines of code (correlation with effort: ~0.3), number of PRs, or story points (slightly better at ~0.35). These metrics are, frankly, terrible proxies for productivity. We’ve developed a custom model that analyzes code and its impact directly, with a far better 0.94 correlation. The result? A standardized engineering output…
TypMoDec 2025 · typmo.com · ▲154Hello HN! I’ve been working on a small tool that helps you move from quick wireframe experiments to solid, production-ready prompts. As a designer, I’ve always felt that getting the structure right early saves a ton of pain later. TypMo leans into that idea by grounding everything in IA-style wireframes- fast to create, easy to iterate, and perfect for figuring out what you actually mean before throwing prompts at AI. I’m now pushing it a step further with a lightweight DSL. Still early, still rough around the edges, but with some AI help it’s starting to feel real. Would love to hear what…

Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…
