    The Critical Need for Software Architecture Practices in Software Development Process
    (Computer Engineering and Intelligent Systems, 2012-01) Gambo, Ishaya; Ikono, Rhoda; Iroju, Olaronke; Omodunbi, Theressa
    Software architecture is the master plan of every reliable software system. It is the building block of any kind of software system which greatly determines the success of the system. This paper argues that every system needs a good architecture and that requires the use of good architecture engineering practices in a software development process. The paper recognized software architecture practice as a discipline pervading all phases of software development and then identifies some of the pertinent areas where architectural practice can be used based on a framework. In addition a model showing how software architecture fits into the phases of a generic software development process lifecycle was presented. The model is to enable software developers and acquirers to use effective software architecture practices during software development in order to exert significantly greater control over software product qualities.

    Software Performance Quality Evaluation of MINPHIS Architecture using ATAM
    (2010-05) Gambo, Ishaya; Achimugu, Philip; Soriyan, Abimbola
    Software architecture evaluation plays an important role in the validation of quality models of software systems. This paper is based on the research carried out where the Architecture Trade-off Analysis Method (ATAM) was used. ATAM was chosen and used because it provides insight into the way quality attributes are mapped onto architecture and also shows the trade-offs existing between the identified quality and others. The evaluation was based on the developed Software Architecture Scenario-Based Performance Quality Model (SASPUM). The paper presents the results of the analysis with ATAM by providing the set of scenarios and their prioritization from brainstorming, the utility tree, the risks discovered and non-risk documented; the sensitivity points and trade-off points found. The evaluation supports the fact that performance can be identified as a software quality attribute, which is part of the execution model of software system determined by the architecture of the software system, and that is suitable for software architectural evaluation.
