I filled in a spreadsheet right after it was given to me regarding what it would take to deliver on some customer requirements. During a later team call I gave my brief analysis based on the spreadsheet. I also asked several questions to give me the understanding I needed to fulfill my duties. After the call my boss and two other senior people reached out to tell me what a great job I did. The funny thing is I probably only spent 30 minutes preparing the spreadsheet for the call. Yet my results were clearly perceived as an outsized contribution to the team.
