You can observe a business process in many ways, ranging from a quick walk-through of an office or plant to doing the work yourself. A quick walk- through give a general understanding of the layout of the office, the need for and use computer equipment, and the general workflow. Spending several hours observing users at their jobs helps you understand the details of using the computer system and carrying out business functions. Being trained as a user and actually doing the job enables you to discover the difficulties of learning new procedures, the importance of a system that is easy to use, and the stum, bling blocks and bottlenecks of existing procedures and information sources.
