Parallel Execution and the Magic of 2<\/p>\n

That’s my second presentation, at 2:15 today. I’ve thought long and hard about this one and hope I’ve made the right decision. I was concerned about how to encapsulate a 50+ page paper into a one hour slot. I hate presentations which are full of detail, rushed, badly thought-out and throw a ton of slides up so quickly that nobody walks away with any meaning<\/span>.<\/p>\n

So here’s what I’m going to talk about<\/p>\n

    \n
  1. Why I decided to write about this subject and I’ll reference Cary’s paper briefly.<\/li>\n
  2. What decisions I had to make early on in the process about the test environments.<\/li>\n
  3. Talk a little about the test scripts and tools I used, but not walk through the scripts in detail.<\/li>\n
  4. A few key results and where I think I made mistakes. <\/li>\n
  5. Some initial thoughts on what the results mean.<\/li>\n
  6. Suggestions for others who might try similar test exercises, based on my experience of this one. <\/li>\n
  7. What I’d like to test next<\/li>\n<\/ol>\n

    I generally hate fluffy presentations that lack any technical content, but this is going to be very light on technical content because I think the paper is there for anyone to read and spend more than an hour over. I’m also conscious of the fact it’s the last afternoon and I want to try to make it bearable if I can.<\/p>\n

    So, that’s fair warning (are you listening, Eric – it’s going to be a presentation, not a course! 😉 ) and I’ll make it clear at the start of the presentation too so that people have time to hit the exits if it’s not for them.<\/p>\n

    Personally, I think the whole process makes an interesting story anyway, and a light presentation will add something to the paper and hopefully encourage people to try a similar exercise for themselves. I hope I’m right!<\/p>\n","protected":false},"excerpt":{"rendered":"
