We spoke at a great event for in-house talent this week (alongside sponsors Reed.co.uk) and while getting our content together I realised what i like to see when i attend these sorts of thing as a delegate and therefore to make sure what we talk about and how we talk about it - fits that bill
1. Most obviously - none of us want to attend for content/info/research and be sold to for 45+ minutes. We are all grown-ups and clearly the organisers are generally doing it for business reasons but make the selling bit either very short or very much implicit.
2. Not all that keen on wonderful case studies where everything goes right, results amazing, budgets plentiful as in our experience that's not how the real world works. We all learn more from the difficult bits than the easy bits - yes? I have never yet had someone say to me I don't think you are a great partner/supplier as the example you showed us clearly did not go perfectly.
3. This may be my personal weakness and slight ADHD - but keep an individual session to maybe absolute maximum 40 mins - as my brain cant cope after that.
4. The organisation of event is really important - have a nice venue, welcome the attendees, have people on hand to chat, try and start (and definitely finish) on time.
And as a speaker - I always want to seek honest feedback so that I can improve in future but only on one condition that the feedback is "you were really good and everyone thought so".
