My manager has asked me to complete a few pages of slides and she has expected that these slides are easy to produce.
However, I spent more time than she had expected due to data constraints. She thought the data could be easily obtained but instead I had to spend time doing desk researches to dig out those data.
Would like to seek your advice on how to better align expectation and work more smoothly with a senior under such situation? I think it is quite common to face the situation that boss wants a piece of info, but in reality those info are hard to find or will take longer time. What is the best way to communicate the situation, instead of letting the senior feel that I spent more time on the task than she expected? Thanks in advance!
