I was talking to the directors of one of the departments at an MNC. She told me that one major challenge she observes with the team is that they are very hesitant to make calls to customers or people from other teams. They often send an email or a message and wait endlessly for a response. Occasionally, they send follow-up emails.
In my opinion, if you want a response or any action to be taken by a person from the customer side, from your team or from another team, it would be great to pick up the phone, make a call, talk to the respective person. Once you discuss the matter over a call, then you can use the emails to keep a record of what you discussed over the call.
When we do this, we will have much greater chances of getting the work done sooner and we will also have a written record that is shared with both the parties involved.
This is a powerful strategy, it always works for me.
