The most valuable skill you can have as a junior developer is the ability to worry.

Advice I've often heard from senior developers is to "delegate responsibilities, not tasks". The idea is that you ask a junior teammate to take ownership of delivering an outcome without being specific about how to do it. This gives them autonomy and flexibility, providing enough room for them to come up with a creative solution on their own. They'll also learn a lot by pushing their own boundaries in the process. If you only delegate tasks, you'll artificially limit what your teammate can do and prevent them from achieving a truly excellent result.

Sounds great, but concretely how do you go about delegating responsibilities? Nobody explains that part. Sometimes it seems obvious, like asking a teammate to "reduce the number of user-visible HTTP 500s by 90%" without any guidance. The result you're looking for is quantifiable. There are many ways to do it (e.g., better tests, more logs, profiling). Asking someone to take responsibility for improving such a metric is straightforward.

But important goals are usually much more amorphous, like "make sure our most valuable customer is happy". There are metrics in there, sure, but the hardest parts are addressing the human factors: Is the customer confident in our product? Are they satisfied with our team's level of attentiveness? Does our roadmap align with their long-term needs? Are they considering switching to another provider? You can't easily quantify the answers to these questions or measure how software development causes incremental improvements to them.

How do you ask someone to be responsible for such an open-ended goal?

My approach is to ask them to "worry on my behalf" about the goal. Worrying is anticipating problems before they happen. Worrying is not taking for granted that everything will continue as planned. Worrying is finding and fixing bugs before anyone else notices. Worrying is being pessimistic about the quality of our codebase and the stability of our infrastructure. Worrying is identifying and mitigating risks in advance. Worrying is verifying the strength of relationships with more communication. Worrying on my behalf is considering everything that might go wrong so I don't have to. This is what I expect from people who take on responsibilities.

Delegating worries transforms my role as the technical lead into one where I'm listening to my teammates to figure out what needs to happen, instead of the other way around. I still ask many questions to fully understand issues and their severity. Then I reprioritize what our team will do across all of the various worries that comprise our project. Running a team this way reduces my responsibilities to 1) are the worriers I've delegated to worrying enough? and 2) is there anything new that I should be worried about? It's a more efficient use of everyone's time.
