No historical data exist on related technologies, techniques, and suitable software development process models. Some of the most critical consequences to be expected are unreliable project planning, incorrect effort estimates, and high risk with respect to process, resource, and technology planning. Under these circumstances, the quality of the target application turns out to be very hard to predict. This chapter presents examples of wireless solutions engineered following the approach discussed in the book. Two pilot projects are highlighted from different perspectives, such as engineering lifecycle, technology, and architecture. Special attention is given to the analysis of historical data gathered from the pilot projects [2], [3]. The chapter aims at giving managers and developers a sense of the behavior of projects in the wireless Internet domain by presenting the experience gathered through the development of pilot services within the context of the WISE project. The pilot services were developed following the iterative and incremental process described in chapter 2. During each of the three iterations, the development focus was placed on a different set of requirements [8]. The first iteration took place during the period December 2001 – December 2002 (13 months), the second iteration during the period February 2003 – October 2003 (9 months), the third iteration during the period November 2003 – September 2004 (11 months). Figure 1 shows the time distribution of the three iterations.
