Okay, sure, you can watch a coder in real time, but most of the time people don't need a coder, they need a developer. A developer has project management and other "soft" skills. Coding is the hammer and the nails... you have to know what you're creating before you start to build it. Most of the time you would see the developer typing up emails, creating diagrams and flow charts, writing executive summaries, managing their agile tracker, consulting on a conference call, researching documentation, etc.
I'm so tired of people thinking that software engineering is about coding. It isn't about coding, it's about developing real-world technical solutions of which coding is a relatively small part.
