Chapter One — 1.1 Background to the Study

Organizations that depend on point of sale systems are under increasing pressure to modernize, and Information Architecture Design has emerged as one of the more promising avenues for doing so, given its demonstrated impact in related domains.

In practice, however, adoption of information architecture design within point of sale systems has been uneven, and its actual impact on perceived usability is not yet well understood in a rigorous, evaluable way — a gap this study is positioned to address.

1.2 Statement of the Problem

Existing approaches to perceived usability within point of sale systems remain largely reactive and fragmented, with little systematic use of information architecture design despite its demonstrated value elsewhere. This study addresses the resulting gap by designing and evaluating a solution built specifically around information architecture design.

1.3 Objectives of the Study

1. To design and implement a information architecture design-based approach to improving perceived usability in point of sale systems.
2. To evaluate the effectiveness of Information Architecture Design in enhancing perceived usability within point of sale systems.
3. To identify the key requirements and constraints relevant to deploying information architecture design in this context.
4. To assess user and stakeholder perception of the resulting system.

1.4 Research Questions

1. How can information architecture design be applied to improve perceived usability in point of sale systems?
2. How effective is Information Architecture Design at enhancing perceived usability within point of sale systems?
3. What requirements and constraints are relevant to deploying information architecture design in this context?
4. How do users and stakeholders perceive the resulting system?

1.5 Significance of the Study

Beyond its immediate technical contribution, this study offers value to organizations evaluating whether to invest in information architecture design for their own point of sale systems, and contributes to the broader literature on applied UI/UX design by documenting a concrete implementation and evaluation case.

1.6 Scope of the Study

As a PhD-level study, its scope is confined to designing and evaluating a information architecture design-based solution for point of sale systems, focused specifically on perceived usability; broader deployment considerations fall outside this scope.
