Usability requirements for COTS based systems

The paper proposes a methodologyhow to transform business goals and objectives into supportingsoftware requirements. The proposed approach is based on ideas beyond the Zachman’s framework. However both lines and columns of the Zachman’s framework are interpreted in quite different way. The left column of the proposed framework is Why column. At the top level it describes business goals and objectives. Other columns are interpreted in the way allowing formulating requirements that step-by-step can be flowdown into detailed and measurable software requirements. For example, the Who column associates business goals and subgoals with the particular roles (positions) that in some way contribute to their implementation and for each role describes performing business tasks. User interface requirements and usability requirements are derived later from this information. The main advantage of the proposed methodology is the possibility to ensure better strategic alignment of software requirements.

Usability Evaluation Methods

Given the emergent need for usability, during last year’s traditional development processes have been extended for enabling the fulfillment of usability requirements. Usability Evaluation Methods (UEMs) have been therefore proposed at any stage of the development process, to verify the usability of incremental design artifacts, as well as of the final product. This chapter surveys the most emergent UEMs, to be adopted during the whole lifecycle of Web information systems for promoting usability. For each evaluation method, the main features, as well as the emerging advantages and drawbacks are illustrated. Some future trends, related to the need of evaluating the usability of UEMs are also discussed.

Behavior Characteristics

The initial progress towards the design and development of a framework for automating the process of integrating experimental data with stakeholder specifications describing usability requirements, along with multiscale models for tailoring material and structural behavior characteristics is reported in the present paper. The proposed framework consists of a layered architecture that is comprised of three main layers. The first layer involves the computational infrastructure that implements the low level computational container that encompasses the computational codes that enable the modeling of the forward problem for various physical problems at specific time and length scales. The second layer of the framework implements the cascaded and hierarchical implementation of the inverse problem in terms of a composition of discrete event system and differential equation system specifications. The third element of the proposed architecture utilizes Category theory abstractions and their computational implementations to provide the necessary infrastructure for automating the process of developing synthetic specifications driven from experimental data and performance requirements related to the design and use of material and structural systems.
