Once you’ve written your strategy’s exploration, the next step is working on its diagnosis. Diagnosis is understanding the constraints and challenges your strategy needs to address. In particular, it’s about slowing yourself down from jumping to solutions before fully understanding the nuances and constraints of the problem. If you ever find yourself wanting to skip the diagnosis phase–let’s get to the solution already!–then maybe it’s worth acknowledging that every strategy tha...| lethain.com
At some point in a startup’s lifecycle, they decide that they need to be ready to go public in 18 months, and a flurry of IPO-readiness activity kicks off. This strategy focuses on a company working on IPO readiness, which has identified a gap in internal controls for managing user data access. It’s a company that wants to meaningfully improve their security posture around user data access, but which has had a number of failed security initiatives over the years.| lethain.com
In my career, the majority of the strategy work I’ve done has been in non-executive roles, things like Uber’s service migration. Joining Calm was my first executive role, where I was able to not only propose but also mandate strategy. Like almost all startups, the engineering team was scattered when I joined. Was our most important work creating more scalable infrastructure? Was our greatest risk the failure to adopt leading programming languages? How did we rescue the stuck service decom...| lethain.com
In early 2014, I joined as an engineering manager for Uber’s Infrastructure team. We were responsible for a wide number of things, including provisioning new services. While the overall team I led grew significantly over time, the subset working on service provisioning never grew beyond four engineers. Those four engineers successfully migrated 1,000+ services onto a new, future-proofed service platform. More importantly, they did it while absorbing the majority, although certainly not the ...| lethain.com
In Jim Collins’ Great by Choice, he develops the concept of Fire Bullets, Then Cannonballs. His premise is that you should cheaply test new ideas before fully committing to them. Your organization can only afford firing a small number of cannonballs, but it can bankroll far more bullets. Why not use bullets to derisk your cannonballs’ trajectories? This chapter presents a series of concrete techniques that I have personally used to effectively refine strategies before reaching the cannonb...| lethain.com
Shortly after a senior leader joins a new company, sometimes you’ll notice them quickly steer the organization towards a total architectural rewrite. Perhaps this is a switch from batch to streaming computation, perhaps a switch from a monolith to a services architecture, perhaps it’s a rewrite into a new programming language. If you take a few minutes to reflect, I bet you can identify several times where you’ve had this experience. Regardless of the proposed technical change, it’s a...| lethain.com
From their first introduction in 2005, the debate between adopting a microservices architecture, a monolithic service architecture, or a hybrid between the two, has become one of the least-reversible decisions that most engineering organizations make. Even migrating to a different database technology is generally a less expensive change than moving from monolith to microservices or from microservices to monolith. The industry has in many ways gone full circle on that debate, from most hypersc...| lethain.com
Whether you’re a product engineer, a product manager, or an engineering executive, you’ve probably been pushed to consider using Large Language Models (LLMs) to extend your product or enhance your processes. 2023-2024 is an interesting era for LLM adoption, where these capabilities have transitioned into the mainstream, with many companies worrying that they’re falling behind despite the fact that most integrations appear superficial. That context makes LLM adoption a great topic for a ...| lethain.com

The Silicon Valley narrative centers on entrepreneurial protagonists who are poised one predestined step away from changing the world. A decade ago they were heroes, and more recently they’ve become villains, but either way they are absolutely the protagonists. Working within the industry, I’ve worked with quite a few non-protagonists who experience their time in technology differently: a period of obligatory toil required to pry open the gate to the American Dream.| lethain.com
