In other words, social relationships are not easy to reestablish”  Experiment: Daycare Late Pickup treatment, but it can help push us in the right direction.”  Agile tie-in: Scrum and the use of time boxes The High Price of Ownership – Why We Overvalue What We Have  Example: Duke basketball tickets from each tent must check in, else your tent moves to the back of the line, 48 hours before game time, when air horn sounds every study must check in  Experiment: What would the students who have a

A “world-class” education system about it. They’ve dubbed their new approach SMART— Specific, Measureable, Attainable, Relevant, and Time-bound. In other words, they want to use Scrum. And, in fact, they are. The office of the Chief Information

repetition and practice is the prerequisite to mastery. The outcomes of the Third Way include allocating time for the improvement of daily work, creating rituals that reward the team for taking risks, and introducing “The wait time is the ‘percentage of time busy’ divided by the ‘percentage of time idle.’ In other words, if a resource is fifty percent busy, then it’s fifty percent idle. The wait time is fifty percent unit of time. Let’s call it one hour. So, on average, our task would wait in the queue for one hour before it gets worked. On the other hand, if a resource is ninety percent busy, the wait time is ‘ninety

THE LEAN MOVEMENT 1. manufacturing lead time required to convert raw materials into finished goods was the best predictor of quality, customer stay the same—due to chaos and entropy, processes actually degrade over time. 2. We improve daily work by explicitly reserving time to pay down technical debt, fix defects, and refactor and improve problematic

impediments, criticism, and abuse. I have so much fun working alongside you.” – Mark Schwartz Last Time in Part One Planning: The idea that we should make a plan and then stick to it is a terrible idea problem.  if we mandate that projects reuse code whenever possible, each project may have to spend time searching archives of available code to find something that is a near fit, and then deal with the intangible, latent capabilities—potential that is, for the moment, hidden.  The EA asset evolves over time through incremental investments.  Managing the EA asset is an art, just as all strategic management

That is precisely what we do not do in an Agile approach. and talk technology—at least some of the time.

simultaneously. Key Measures Mean-time to production: the average time it takes from when new software features are required until they are running in production. Average lead-time: how long it takes for a new production environment. Production failure rate: how often software fails during production. Mean-time to recovery: how long it takes applications in the production stage to recover from failure. Key
