1	A Product Line Enhanced Unified Process
2	Agenda Motivation UPEPL-Unified Process Enhanced with Product Line Case study with a mobile RPG product line Discussion and Conclusions
3	Background Role-Playing Games (RPG) on mobile devices: similar but also different features running on Moto E680 developed by four developers, as unique products
4	Motivation Whenever you develop a software system, you are not developing a single system, but a family of systems. Pros and cons for Unified Process Current OO and CBSE fall short in dealing with effective reuse
5	UPEPL-Unified Process Enhanced with Product Line may start from the end of the first iteration, or after the release of some products in the product family just like the typical process of product line engineering Adding product line related activities and assets to each phase of the traditional UP.
6	Activities in inception phase
7	Activities in elaboration phase
8	Activities in construction phase
9	Case Study with a mobile RPG product line Role-Playing Games (RPG) on mobile devices: similar but also different features running on Moto E680 developed by four developers, as unique products
10	Inception We could achieve the following with a RPG-PL Unify design of the four RPGs ease of evolution Share optimization strategies across RPGs performance issues Cut development cost of other similar RPGs new features, running of many platforms Without compromising performance or quality
11	Inception-continued Similar software must run on many types of mobile devices Many brands and models of mobile devices differ in platforms, communication protocols, display units, memory size, etc. 640x200 color screen vs. 100x80 mono display 80M memory vs. less than 100kb memory RPGs must perform well on all those devices Development cost, time-to-market are factors
12	Elaboration
13	Feature diagram for RPG domain
14	From four RPGs to Product Line
15	Refinement Steps: RPG-PLA Refine Climb-PLA to build RPG-PLA Identify groups of similar components across four RPGs for we unify them with generic meta-components Address unique features of three other RPGs for we design meta-components to be adaptable Add more optimizations and propagate to all four games via RPG-PLA
16	Construction
17	Discussion
18	Discussion-continued Enhanced conceptual clarity, uniformity and integrity of the design which F. Brooks calls “the most important consideration in system design” (The Mythical Man-Month ) Easier to trace the impact of changes less number of modifications to implement an enhancement change propagation from generic to concrete instances reduced risk of update anomalies Reduced size of RPGs by 25%
19	Conclusion UPEPL could go side by side with traditonal UP Disciplined product line could help to improve return-of-investment generative techniques can turn similarities into productivity gains build generic design solutions unifying similar structures
