Tons of comments saying it’s none of your business. I disagree. If you care, you can’t stop caring. You’ll drive yourself nuts watching this coworker continue to be a drag on the company. Either find a new job or swing for the fences and try to make the company better. I want people at my company who give a damn. If a coworker slacking off is pissing you off, it shows me that you actually care about the company, the product/clients and progress. If you “mind your own business”, it shows me that you just care about your paycheck. The questions I’d be asking myself in your position is what is it about the company workflow / accountability structure that allows this to happen? Research better options, put together some ideas. Find out if you like problem solving at that organizational level. If you don’t, then maybe find a new job. If you do, then tactfully look for someone who is successful at the company and seems to share your passion for getting stuff done, even if they’re a level or two above you. You can try to pitch your ideas to them and it’ll be apparent pretty quickly if they think you’re a godsend or a troublemaker. The Socratic method can be useful, asking questions like: “Why don’t we track individual progress?” Or “Why don’t we use [method from your research] here?”. It’s a less hostile way to approach the problem through curiosity and people will send you political signals like: “Oh, I tried that before and Bob put his foot down.” Or, “Wow, you sound just like Sally. I bet she’d like to talk to you about that.” Sometimes these problems are political rather than organizational. Even just asking questions to your superiors shows that you care and will probably get you some bonus points, unless you’re at a really crappy company where everyone is doing their best to skate by and those who aren’t skating by are persecuted. The most aggressive approach that might work is anonymizing them and simply saying: “I really want this company to achieve [company goal] and I’m worried that we’re not all working efficiently enough to make that happen.” Or, “I’m really needing more support from [other department] in order to deliver on [your commitment].” You might be asked for details and names, which is kind of a point of no return. Action will probably be taken towards you or them. Anyway, there’s a chance you ruffle some feathers, but there’s also a chance you draw some positive attention. Or you can keep your head down like others are suggesting, but the fact that you care this much, I doubt you’ll be able to continue to do it without stifling your own ambition to make the company better, and why would you want to do that?
