I have so much fun working alongside you.” – Mark Schwartz Last Time in without requiring changes to the whole ball of EA. It has a robust, automated regression test suite, so that new development does not cause expensive break-fix activity. It has good monitoring tools human beings are making decisions, if an IT product can be acquired “off the shelf,” it is better to do so than to build it.

A Seat at the Table - IT Leadership in the Age of Agilitystill a given, but we want to drive out as much as we can until it stops being cost-effective to do so. We can take this as yet another definition of what it means to be Agile. Why do people feel like becomes truly necessary to hit a schedule milestone, then we can adjust our scope to be sure that we do so. The importance that we have attached to the timing of FOC is just another example of the misconception are comfortable with the ideathat we will break things in testing, because the end result of doing so is that we can make a decision more quickly and with more good information available. “Failing”0 码力 | 7 页 | 387.48 KB | 6 月前3
The Phoenix Projectloops. The goal of almost any process improvement initiative is to shorten and amplify feedback loops so necessary corrections can be continually made. The outcomes of the Second Way include understanding fifty percent idle. The wait time is fifty percent divided by fifty percent, so one 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 would wait in queue nine times longer than if the resource were fifty percent idle.” I conclude, “So, for the Phoenix task, assuming we have seven handoffs, and that each of those resources is busy ninety0 码力 | 3 页 | 154.45 KB | 6 月前3

No Was your plant able to ship even one more product per day off or reduce operating expenses? No, there is a union… Did your inventories go down? I don’t think so… Jonah ends the conversation with the question: “Alex, you cannot understand the meaning of productivity else ahead of it ● Wait time - the time the part waits, not for a resource, but for another part so they can be assembled togetherFor parts that are going through bottlenecks, queue is the dominant0 码力 | 6 页 | 100.81 KB | 6 月前3

Continuous Delivery and DevOps place the entire value stream in the hands of that small team so that it can optimize the whole – a term of art in lean thinking – and be empowered as a team to own projects are evidence that a mistake has been made.
