It's interesting you call out a year as a time span. I have no idea what the goals will be in a year, let alone how I'll code it. A year seems like a really long time, but also just short enough to justify adding extra work in early. My timeframe is more like a week to a month. Obviously different orgs will have different time windows for real reasons.

Most companies have a revenue goal for the current year. From that revenue goal you can infer what software capabilities need to be obtained.
