First, tar
Different people watching the same project will have different understandings and requirements, and the same project will have different understandings and requirements in different periods. But a project will always be limited to: time, fund, current technology level, etc. The existing conditions are always to meet the desire of the project, and it is exactly the desire of people.
For example, now there is a project released project, the initial imagination is that the product information can be broodowed online, but with the progress of the project, the customer thinks necessary to add a browsing, OK, little means, Plus. Shortly after giving feedback, the customer reflects that many people feel good after browsing. What doesn't add this function? Do not add, obviously it will be unsatisfactory; add, then you must join Order management, delivery management, etc. When is it, and it is necessary to re-talk about the prices of the project, it is bound to affect other work.
In my opinion, if you choose to add function, then choose to jump into the tar. I tend to end the items on time and check the payment on time according to the original provisions of the contract. As for the new customer, according to the overall operation of the company, there is no strength and time to complete, if you can, adjust the company's operation plan, collective human resources, and discuss and operate in a new project. If you don't work, you can coordinate the development or give up.
Second, 1/3 1/6 1/4 1/4
I agree with the first one, but after 3 in real projects can I do this? For example, the second one, a large extent is affected by the technical level of the team, a Team, which is fully consisting of masters, can be encountered, so it is necessary to stay more time to encode, if everything goes well, you can take more The subsequent part of the subsequent part, of course, when dividing the encoded time, it is necessary to indicate how much time is to solve the technical problem, not normal encoding. For testing, unit test is often measured while developers, and the project is generally completed, so can it be given half of the 1/4 in the encoding, and half of the mix is in the encoding?
