# Writing

> **Bottom line:** Articles on AI product development and technology leadership. Each opens with the conclusion, then the reasoning and evidence.


- [Build, buy or wait: an AI decision framework for technology leaders](https://manasdasgupta.com/writing/build-buy-or-wait/) (2026-09-20): Build an AI capability only when it is core to your product and you can evaluate it. Buy when it is commodity and a vendor can show evaluation results on your data. Wait when neither is true: model capability and prices change fast, and a six-month delay is often the cheapest option.
- [Evaluation-first: why AI products should be tested before they are built](https://manasdasgupta.com/writing/evaluation-first-ai-products/) (2026-09-15): Write the evaluation set before you build an AI feature. It forces agreement on what good looks like, turns quality debates into numbers, and catches regressions whenever a prompt or model changes. Start with 50 real examples and add every production failure back in.
- [One-to-ones that surface problems early](https://manasdasgupta.com/writing/one-to-ones-that-work/) (2026-09-05): A good one-to-one belongs to the report, not the manager. Let them set the agenda, spend most of the time on what is blocking or bothering them, and keep status updates out. Hold it weekly, never cancel twice in a row, and write down what you agreed.
