I recently attended a trade show and showed interest in several products. So much interest that the conversation when to level of business cards and not just the normal trade show scanner.
Now I wait.
While I can call them, they have my number, product i am interested in, etc. It would be a lot quicker than me calling into a company and transferred around to finally leave a message in a voice mail.
The word on follow up, is have a process.
For me I have a follow up folder in my email, blackberry and also a hanging folder at my desk. These are set up so that I can capture the follow up in the moment. If I am given a document I place it in the folder. If I need to call someone, I place a task in my blackberry and if I have a task for work, it is either in my to-do or follow up folders. I check these tickler files each week to see what i can do or if i need to defer them till a later date.
I have found these simple collection areas to be very helpful.
