PW-PlanTe: uma estratégia para melhoria de processo baseada em atividades de planejamento e teste

Abstract

Background: The process quality model implantation on small enterprises requires an adjustment for this type of enterprise and the difficulty to reach this objective is harder due to the restrict amount of different type of resources. To support the process improvement in this context, concerning the software planning activity, the strategy PCU|PSP was defined. It is based on Use Case Points and Personal Software Process. Aim: The objective of this monograph is to present the PWPlanTe strategy, which is an evolution of the PCU|PSP strategy. PW-PlanTe generalizes the techniques used in the planning, applies well defined iterations aiming to be in conformance with the agile paradigm development, and defines a testing process. In addition, PW-PlanTe is supported by a set of free tools that facilitate its implantation. Methodology: Considering that PCU|PSP is naturally adherent to the agile methods, it was studied and generalized in relation to the planning issues aiming to make it even closer to the Scrum framework. After that, the testing process for small enterprises was defined and the free tools were identified aiming to establish a support for the strategy steps application. Results: PW-PlanTe was applied in three systems that were under development by the small enterprises which participated of this research. In two of the four systems where the planning activity support was explored, the results showed that the strategy facilitates the determination of the work to be done in each iteration. In three of the four systems where the testing activity support was explored, various defects were found by the application of the strategy and were not found without its application. Conclusion: Based on these results, evidences can be identified on the contribution of the strategy for the implantation of the software development process improvement in small enterprises, both for the planning activity as well as for the testing activity. Additional studies should be done aiming to make these results more evident.
