Chapter 7 Why is the Babien Tama failure
1. The exchanges and communication between projects is an important factor in the smooth and successful project.
2. The lack of exchanges cause progress disaster, and the unreasonable function and system defects have emerged. As work, many groups slowly modify their programs, scale, and speed, and they have changed some of the effective input and output results usage.
How the team communicates with each other:
Clearly define the interior of the group and make full use of the phone, which can encourage a large number of telephone communication, thus achieving a common understanding of the written document.
General project meeting. In the meeting, a team a brief technical statement was conducted. This method is very useful, it can clarify the fine misunderstanding of hundreds of thousands of small misunderstandings.
At the beginning of the project, you should prepare a formal project work manual.
3. The project work manual is not an independent document, which is a structure of a series of documents that must be produced by the project.
All documents of the project must be part of this structure. This includes the purpose, external specifications, interface description, technical standards, internal descriptions, and managing memos.
4. Use the project work manual:
Technical description is almost essential. If someone will check a series of related user manuals on a part of hardware and software. He found not only ideas, but also many of the texts and chapters that can be traced back to the earliest memo, these memorands make recommendations or interpretation of the product.
The correct document structure is very important. The project work manual is designed in advance, ensuring that the structure of the document is specified. In addition, there is a document structure, and later written text can be placed in a suitable chapter.
Control information is released to ensure that information can reach all the hands that require it.
5. The purpose of team organization is to reduce unnecessary exchanges and cooperation. The way to reduce communication is to divide and limit the scope of responsibility. When using human division and responsibilities, the tree management structure reflects the need for detailed communication.
Chapter 8 Chest has a bamboo
1. Problem: How long does system programming take? How much work is required? How to estimate?
2. The workload is a power function of the scale.
Portman's data: The time spent is about twice the estimated time.
ARON, HARR, OS / 360 data: Productivity will show significant differences depending on the complexity and difficultiness of the task itself.
Carbato's data: For a commonly used programming statement. The productivity seems to be fixed. This fixed productivity includes the case where the comment is required and there may be errors. With proper advanced language, the productivity of programming can be increased by 5 times.
