Developing a music player on the android platform is a whole new challenge. This time, through the actual combat of the android QQ music project, I have summed up some methods and experiences, hoping to provide some valuable reference whatsapp Database and help for the design of the mobile platform, especially the multimedia. Introduction of Product Definition Statement ( Application Definition Statement ) I believe that most designers have had the experience: in the process of product design, designers and product managers kept pking, expressing their opinions, and even blushing, slapped the table and turned their faces. The target "both sides deeply blamed whatsapp Database themselves and expressed "lack of communication". Constantly pk each other, communication is absolutely enough, but we lack the tools to communicate effectively.
This time, we decided to cut in earlier, and introduced a "product definition description" at the initial product planning level (for the app-plication definition statement, please refer to "iPhone Human Interface Guidelines"). Note: The definition of whatsapp Database ADS is also an iterative process. Changes in the external environment and problems in subsequent processes may have an impact on the original ADS, which needs to be re-evaluated, revised, or even denied again. However, in any case, it must be ensured that the entire team is responsible for the ADS. There is a whatsapp Database common understanding. Second, subdivide the scene, deduce the demand from the scene, and derive the design from the demand Once a unified understanding has been established at the strategic level of the source, our next work is based on it.
The conception of the scene needs to be based on a high degree of cognition. At this time, the entry of user research is quite critical. User characteristics, preferences, usage habits... The more you understand the user, the closer the scene will whatsapp Database be to reality, and the more details you can discover. These provide a strong basis for subsequent design decisions. There are many interesting findings in the objectively constructed scene. For example, when users play local songs, they tend to be hesitant to select the first song, but they don’t care much about whatsapp Database subsequent songs. From the careful analysis and scrutiny of the scene, it is easy to clarify the requirements of the product. Corresponding to the above findings, the following requirements are deduced.
