The work that I do involves a lot of thought, numbers, and time. There is pressure to work on as much and as fast as possible, but also to make sure that our answers are accurate; accuracy most importantly.
When I finally have the work ready, I check it over, and then I send out the results. However, I keep making little mistakes, as I am tired and anxious to move on to the next work item.
For example, I might save the workbook on the last worksheet, instead of the first one, confusing the client that I sent them the wrong workbook (they just need to change the worksheet). Or perhaps I typo a date range or number, causing a big alarm. Or maybe I forgot a recipient in the email. Yes, a mistake every now and then is fine, but nearly every item of work that I do has a little mistake in nearly every revision. These little mistakes are adding up and I am worried that others are starting to feel that I am incompetent.
Question: How can I get better at checking my work? Where do I even begin to personal development my quality control skills?
We do not have Q&A, and each person is expected to Quality check their own work. Unit testing is not an option, but I have gotten better with making sure that what I output agrees with other things that have been previously outputted.
