Lessons Learned – Interface Development • Swing as Prototyping Tool – Swing has incredible flexibility and control. – Large memory footprint – Swing has a steep learning curve for novices and it is also difficult to master. • Choice of Layout Manager – Grid. Bag. Layout versus Table. Layout • Usability Concerns – User interaction – Organization of information – Sizability (Maximize, Minimize) December 7, 2006 INFM 718 B Fall 2006

Lessons Learned – Rapid Prototyping • Essential methodology for user-centered design • Better visualization and communication • No surprises! Prototyping ensures meeting customer’s requirements. • Save time and resources. • Go for minimal functionality. • Be prepared to throw away. Common Problems: • Sometimes clients focus on the wrong things in a prototype which has too much detail. • Clients may get intimidated by an over developed prototype and not feel comfortable to comment on it. December 7, 2006 INFM 718 B Fall 2006

Suggestions for Course Improvement • • • Use of other rapid prototyping tool with visual modeling tool. Flexibility to define project but not specific to clients. Problem: Timeframe is insufficient to develop a usable prototype. More hands-on during class. December 7, 2006 INFM 718 B Fall 2006
