Events Management

hi

im trying to establish a standardised approach handling event management

ive been using a similar structure to this on all my projects and havent had any problems.

weve had a new guy start in the office who uses this method, and i can see why its an easy solution to use too, but not sure if we’ll run into problems.

was wondering if anyone had any thoughts on the correct way to handle this, and what potential problems we may come across.

much appreciated
