What have you learnt in the course of your career that would be really useful for colleagues here on the Learning and Skills Group to know about? It could be totally tactical ('Always begin a public presentation with a full set of lungs') or utterly strategic ("Never begin an L&D plan without first knowing which executive gives you complete support.")
The only thing it has to be is short.
To start off, here's my offering: Never say 'yes' to a training request without first asking 'why?'.
It is vital that you fully develop your training team at the outset (preferably against a recognised accreditation process) in some core principles to support learning e.g. stakeholder engagement, course modelling and design, presentation and delivery techniques, evaluation studies of of ALL blended & own time learning systems. Back this up with studies on coaching/facilitation/mentoring, NLP, TA, ROI, negotiation & assertiveness skills. It does take time.
Short term savings ('..been on a train the trainer..') will result in medium/long term failings in the impact the learner has on the business. A bit wordy I know but I have seen the benefits of applying this method.
if you want people to engage like adults and take responsibility like adults, give them opportunities to learn like adults. Most of us are overjoyed to have left the lecture theatres and classrooms behind!
Make sure the intent is clear. Use that as the lens for everything else. e.g. The intent is to increase customer satisfaction. Therefore will this (this being whatever you're doing) lead to increased customer satisfaction...
