I personally think that the development of projects and software is the same as the factory and manual.
First, from the effect: The specifications from the things produced from the factory are so many, and manual processing can be made into a wide variety of products. Developing software products a software generally a new product, divided into several versions, just from all aspects in line with customer usage, not necessarily suitable for all users, a lot of training needs. For example, Windows series, Photoshop series, Authorware series, etc., which information is a big. The project development is conducted for the customer's needs. The developed software is fully compliant with the customer's operating habits (except for the failure projects), the customer is easy to get started, the training is relatively small, and the most is an operation manual, An illustration, the training time is one or two days.
Second there is a cost: The average cost of the products produced in the factory is always lower than the manual processing, but if the batch is small, the cost of the product is higher than that of manual. The average cost of software products is always compared to a certain customer development software (certainly the cost of selling software products is high (small)).
Again from stabilization: The update period of the factory is relatively long, the life cycle of each product is relatively long, pay attention to the product's upgradeability and the compatibility of the same product, while manual processing Considerations are subjectively determined by the manufacturer, which is not guaranteed, that is, and even the product produced by the same maker is also different.
Finally, from maintenance: The specifications of the products produced by the plant are more secure, and maintenance can form a complete system, while the hand-machined product specifications are different, so maintaining a large extent is the experience of developers. Others want to repair the software to have a long time learning to fully grasp the maintenance methods.
In summary, the list is as follows:
Project factory produces hand-processing products, less types, less types, many versions, many versions, many first development costs, higher, lower, low, low, low, lower, higher, low, low, low It is more difficult to upgradeability and more difficult to maintain more difficult to maintain more difficult than easy to develop cycle longer, long, long, long, short, more difficult, training, less training, more training It is more easy, less training
