My takeaways are that design can be hard and is paramount to the success of products and processes. Attempting to design solutions before the problem has truly been defined will cause headaches. However, taking the time to sketch the entire process will pay dividends in cost savings and quality. Moreover, truly understanding the challenge is usually the greatest design deliverance.
Lastly, the most important takeaway: simple is beautiful. So, make your blog entries short. 6 words on a power-point slide is more powerful. Brevity is next to Godliness.
