Good advice so far. Some more thoughts: - It's better to go in with a tentative understanding and get the SME to correct or elaborate it. Ideally you shouldn't go into a session just to be pumped full of new information. It's very hard to understand complex material without having time to go over it in your mind. - Try to develop a 'big picture' that you gradually expand and refine as you find out more. Early on it might just be a one-page diagram or a few sets of bullet points. As you learn more you might expand each bullet point or blob in the diagram into a paragraph. After a while it should cover things like the purpose of the project/product; its main features/functions; main industries/markets/competitors; main users; their tasks and goals. Think of this as the overview or plan of attack that would have liked to have when you started on the project--a survival guide for your younger self. From time to time, check this understanding with your manager and the SMEs. This will be your solid ground when you go on to drain new areas of swamp. - Remember that your SMEs have probably been immersed in the project for some time and they may have been grappling with complex, low-level details when you come to see them. It's hard for anyone in that situation to step back and give the to someone who's new to it. - Don't try to chase down every unfamiliar concept while you're talking to an SME. There will always be jargon that you don't understand. You need to develop a sense of when to jot down an acronym and keep listening, when you need to stop the SME and ask for clarification, and when something unfamilar is probably not relevant to you so you can just ignore it. - A lot of people pooh-pooh Wikipedia but it's a great resource for technical concepts when you're starting from zero. I can recommend this excellent book: _User and Task Analysis for Interface Design_, by Hackos and Redish Plenty of guidance on how to gather and organise information. Don't be put off by the name--it's equally applicable to tech writers. Good luck. Stuart
