Tweetable Quotes:
Why Slowing Down Software Releases Might Backfire: One of the things that would happen is if you slow down, how you ship to production is you'll have bigger batches and bigger batches, which means you might ship more bugs all at once and have to find them in a bigger QA cycle. — Thanos Diacakis

"I also think we sometimes convince ourselves that we know more than we actually do and that we can plan a really long way out." — Thanos Diacakis

Viral Product Development Mindset: "If you engage engineers and product in these creative discussions, you might find out, oh, I scoped out these 10 things, but turns out the customer gets 80% of the value from this one thing." — Thanos Diacakis

Bureaucratic Bottlenecks in Big Companies: "They try to optimize locally for one particular function rather than optimize globally for shipping things out the door." — Thanos Diacakis

Viral Topic: "Why Every Team Should Read Accelerate": So I think if I give anyone advices, if you haven't read Accelerate, then go read that book. Because it's basically lays out in terms of, and this is in terms of like core technical and procedural sort of infrastructural things that teams ought to have to be productive. — Thanos Diacakis

SaaS Leadership Lessons:
Bias Towards Action Over Perfection
Avoid waiting for perfect plans, especially with innovative projects; instead, learn by doing and iterating.

Increase System Visibility
Make work in progress and team capabilities visible; this surfaces bottlenecks and areas for investment.

Balance Short-Term and Long-Term Goals
Strategic investment in tooling, tech debt, and risk mitigation ensures sustainable delivery and value realization.

Prioritize Collaboration Across Functions
Breaking down silos between product, engineering, and design dramatically accelerates delivery and reduces defects.

Ship Small, Ship Often
Frequent, incremental releases drive faster customer learning, boost agility, and reduce risk.

Cultivate a Shared Language for Outcomes
Use terms like investments and risk (not just features and bugs) to align business and technical priorities and drive meaningful conversations.
