Writing and updating job descriptions is more complicated than people think. During a recent project, I had to work on job descriptions, and I realized how much actually goes into them. It’s not just writing down what someone does all day. It involves figuring out what really matters in the role and making sure it’s relevant over time. It can be hard to know how often to change them or how to word them clearly so that HR, the employee, and managers are all on the same page.
The article Job Worth Doing: Update Descriptions really changed how I think about job descriptions. It said that a bad job description is worse than not having one at all, which makes a lot of sense now. Job descriptions are used in everything from hiring to training to performance evaluations. So if they’re outdated or vague, the whole system can break down. I liked the idea that they should be reviewed at least once a year and also updated whenever there’s a major change in the role.
Another helpful point came from The Definitive Guide to Recruiting in Good Times and Bad. It explained that a lot of companies don’t actually have a real plan for what kind of talent they’ll need in the future, and because of that, their job descriptions usually end up missing the mark. If a company isn’t thinking ahead about how roles might evolve or what skills they’ll need down the line, the job descriptions won’t reflect what’s actually important. That can create problems during hiring, training, and even performance reviews because the expectations aren’t clear or realistic. That’s where HR and upper management need to work together. HR can help write clear and legally sound descriptions, while managers bring insight into how the job might grow or shift over time. If both sides communicate regularly, it’ll be easier to update descriptions as needed and avoid confusion for everyone involved. It also helps with employee engagement because people want to know their role matters and that there’s a path for growth.
