With the pain of practitioners, software engineering, project management, process control, ability maturity, etc. began to be accepted by everyone, and books in this area have also been there. We grow step by step in the theory and practice collision, and project management is somewhat appearance, with at least configuration management and version control, and introduces milestone checks. According to the theoretical theory, the control ability is improved, and the work can be more excited. It is a good thing that is not imagined, life is still a word "busy". In fact, the cause of busy is, a large part is due to the problem of project risk control. First, the company needs a lot of happiness of the risk manager thanks to the growth in reflection, this time is more considering due to the pressure of the work. A few days ago, my friend sent me a book, "" Tsinghua University Press) (Tsinghua University Press) (Tsinghua University Press) (Tsinghua University Press) (Tsinghua University Press) is sometimes touched. The ability of software development in these years is indeed improved, and the quality of the preparation is getting better and better, and it can also serve larger customer groups. Although software technology is improved, there is no difficulty in solving the difficulty of software. When we bring updated software and technology to the user, we also cultivate the user's ability to use and identify, users become mature, demand is more meticulous and harsh, which makes a higher demand for software quality. The development time is not easy to save. Moreover, when we look around, the software company grows like a spring. Like other industries producing excess production, the software industry has basically become the buyer's market, and the competition between software providers is increasingly intense. In the game with software companies, customers use market advantages to take advantage of the peak, software companies must provide better products and lower prices to get orders. In this way, the profit margin left to enterprises is small, and the risk of the company has increased, and risk management is more necessary. Second, how can the company provide better products with lower cost and shorter time with lower cost and shorter time? Size advantages and industrialization is the idea of solving this problem, but China's software companies are small, it is difficult to produce standardized products, which is not easy to form the advantages of scale and industrialization. In particular, the market has formed a concept that software is a very flexible product, which can be changed at will, which has brought more difficulties in achieving industrialization. In the process of contacting customers, customers will inevitably ask questions, if time is too long, it is possible to scare customers. However, now the rhythm of society is accelerating, if the work is short, will it give yourself a tightening? People who have originated in technology often have some heroic colors, which are too high to estimate their own achievements, and sales staff don't know how to develop, and of course, the project will be completed as soon as possible, so the time is often shorter than normal. During the period, since the seeds of the overtime are planted, they will naturally take root in the back. In order to effectively reduce this first risk, I think there are many ways to use: Try to give the project a better external environment, through communication and other means with users, to fight for more adequate development time, don't shoot chests Leave the risk to yourself; to be scientifically estimated the risk of project implementation, changes in people's changes, demand changes, etc. It is necessary to have enough vigilance. If there is time to be relatively small, you must configure more resources. If there is not enough resources, you may have to arrange overtime early, avoid the problem of pre-tightening. The problem in the software development process is endless. If you consider a little risk, it is not necessarily enough. If the heroism is strong, it is hurt or herself. Other risks and estimated risks in the project also have more elaboration in the book.
