What is a technology stack and why the right one matters

A tech stack, also known as a solution stack, encompasses the technologies used in developing a product, such as frontend, backend, database, and queue systems, and selecting the right stack is crucial for product success. A mismatched tech stack can lead to inefficiencies and costly changes, as illustrated by a startup story where assumptions about scalability led to unnecessary complexity and delays in developing a user management feature. To avoid such pitfalls, it's essential for product managers and CTOs to set clear goals and context, such as user reach, quality aspects, scalability, and time expectations, enabling engineers to make informed technology decisions. Collaboration between product managers and tech teams is vital, as it helps align technological choices with business objectives, ensuring that the tech stack effectively supports the product's goals. Product managers who engage in tech stack discussions and ask insightful questions can facilitate better decision-making, ultimately leading to a more successful product.
