Integrating Human-Computer Interaction Development into the Systems Development Life Cycle: A Methodology

Abstract

Incorporating a human computer interaction (HCI) perspective into the systems development life cycle (SDLC) is necessary to information systems (IS) success and, in turn, to the success of businesses. However, modern SDLC models are based more on organizational needs than human needs. The human interaction aspect of an information system is usually considered far too little (only the screen interface) and far too late in the IS development process (only at the design stage). Thus, often a gap exists between satisfying organizational needs and supporting and enriching human users. This problem can be addressed by carefully integrating HCI development into the SDLC process to achieve a truly human-centered IS development approach. This paper examines the roles of HCI in systems development, justifies the importance of considering HCI through out the entire systems development life cycle, presents a methodology for human-centered IS development, and demonstrates how to apply this methodology to develop human-centered information systems.

A survey on user involvement in software Development Life Cycle from practitioner's perspectives

“…UCD [22], UE [20] and PD [21] are usability methods that focus on user involvement in software development process. The importance of HCI, which emphasize on human-centeredness, usability, human factors, user experience, design issues, as well as concerns on the success of businesses, management, and also organizations, has been accepted to some extent by practitioners [2]. Since user interacts with information, technology and task from various contexts [2], each design of software development must consider user involvement to ensure user satisfaction of the product.…”

“…Current SDLC which focuses on functionality is different from the proposed HCSDLC [2] in a number of respects as shown in Figure 1. Several studies by Hoffer et al [1] have revealed that among the many systems development approaches, the SDLC model is a commonly accepted modern structured approach for describing the complex processes and issues in system development.…”

“…If the user is not satisfied with the prototype system, developer will revise the prototype and make it more effective and efficient in terms of the system functionality. On the other hand, based on framework proposed by Zhang et al [2], the revision of the prototype not only on the system functionality, but it should also consider revising the usability and usefulness of the system non-functionality. The ease of use, ease to learn and safe to use should be considered during the revision of the prototype system.…”

“…Thus, this study is conducted to investigate to what extent the user involvement that has been addressed in SDLC process in software development is being practiced. To investigate the user involvement, the Human Centered System Development Life cycle (HCSDLC) proposed by Zhang et al [2] which emphasized on user involvement at all stages of SDLC is used.…”

CHUNK: An Agile Approach to the Software Development Life Cycle

“…HCI includes all aspects of the system that impact its users or other stakeholders. Although the user interface is one of the most noticeable components of the HCI and is key to the systems eventual acceptance, it is not the only part of the HCI development (Zhang et al, 2005).…”
