appears to offer predictability, control, and efficiency, the key values of the contractor-control model. But it doesn’t. Requirements: Requirements are a way of controlling the development team by constraining Characteristics of an Agile governance and oversight model: Before we dive into an Agile governance and oversight model, let’s think about what characteristics such a model should have in order to both take advantage appropriate (what we are typically looking for is opportunity cost). We use a simple, one-page document we call the Financial Summary for this purpose. How to gauge plans: To gauge the plans for the

decisions under uncertainty, and then have the courage to face the consequences. In the plan-driven model, quality was easier to understand.  We specified what the system should do, and then measured quality that, either.  We are constantly making quality decisions, especially in a Continuous Delivery model, as we decide whether the quality of each individual feature is adequate for the feature to be deployed that we have not yet learned to take advantage of, caught up as we are in the contractor-control model of IT. Shadow IT is what happens when the IT organization is unable to meet the needs of a part of

print(len(strb)) #结果是8 ★python3在将str="xxx"转换成3s时，会报错： struct.error: argument for 's' must be a bytes object 需要在传入的字符参数前加b import struct a=b'hello' b=b'world!' bytes=struct.pack('5s6s',a,b) 或者把str转为对应编码的bytes
