What 'improving the product' means will depend on the type of product you select and its purpose. The list of products that we suggest have a clear purpose so 'improving the product' means making it easier to perform the intended tasks. This may not be the case for other products such as games, where 'improving the product' may mean making it more fun to use or making it more aesthetically pleasing. Much of your observation will be concerned with trying to understand what exactly users are trying to do. As you gain a better understanding you will be able to refine your ideas about 'what improving the product' means and start to consider ways of achieving this goal. Having done a preliminary observation you should be able to plan your study. A central issue will be to decide where on the 'outsider-insider' observer spectrum you wish to be. Being an outsider may make the group feel self-conscious so they change their behavior. On the other hand, you have limited time to gain acceptance as an insider. Your choice is also likely to depend on your personality, and to some extent on the data collection and analysis tools that are available. Having colleagues to work with may also influence your choice of approach. For example, two observers working with users in a relatively 'insider' fashion will most likely be easier than one person working on his or her own. If you are still wondering how to proceed, read the interview with Sara Bly on page 387 of the book to get ideas.
