Requirements & Vendor Information Software needs to be user friendly. Support needs to be available. When is your company founded? How many employees does your company currently have? What are the core activities of your company? How is your support organized in our country? Do you have a helpdesk, and what are their opening hours, and what is their response time?
Vendor information What are the platforms your product supports (OS)? What hardware architecture is needed for your product? What infrastructure is needed for your product (please answer for LAN and WAN)?

User interaction steps for a typical user interaction with a generic interactive system
User interaction Punten uitleggen First, the user forms a conceptual intention from her/his goal (for example, a user wants to access a particular project in the repository accessed from the Web site in Figure 2). Second, s/he tries to adapt this intention to the commands provided by the system (in our trivial example, an initial exploration of the Web page is needed to figure out how to realize the intention) and from these (user-perceived) commands carries out the action (for example, the user tries to type some information into the search text field, then hits the "search" button beside it). Then, the user attempts to understand the outcomes of her/his actions (in our example, by examining the page obtained after the "search" button is pressed). This is particularly important for computer systems, where the inner workings are hidden and users have to figure out the internal state only from few hints
User interaction Mismatch between user and system models The gulf of execution The gulf of evaluation Response time Short-term memory (STM) Control and Automation
User Interaction General Principles Know your user Minimizing the load on users Preserving consistencies Ensuring overall flexibility, error recovery, and customization.
