Systems Analysts Have To Consider A Great Many Options For The System

Systems analysts have to consider a great many options for the system architecture. Use an example of a new business information system to respond to the following: Suggest 2 or 3 questions that a systems analyst might ask in order to determine the most appropriate architectural choices for the new system. Show, through a scenario, how different responses to these questions would lead to different decisions. Do not repeat an example from the textbook or one that has been posted by another student.

Introduction

The process of designing a new business information system involves critical decision-making about the system architecture. Systems analysts play a crucial role in identifying the most suitable architecture to align with organizational goals, technical requirements, and user needs. To accomplish this, analysts need to ask pertinent questions that guide their architectural choices. Based on the answers, different development paths and architectural frameworks emerge, leading to varied system designs. This paper discusses three key questions a systems analyst might pose when determining system architecture, illustrated through a scenario of a new retail management system.

Key Questions for Architectural Decisions

The first essential question pertains to the system's scalability and future growth potential: "Will the system need to support a significant increase in users or data volume over time?" This question influences whether to implement a monolithic architecture suitable for small to medium-scale operations or a microservices architecture designed for scalability and flexibility. The second question concerns real-time versus batch processing: "Does the system require real-time transaction processing or can it operate effectively with scheduled batch updates?" The answer impacts decisions between a centralized real-time processing system or a distributed batch processing framework. The third question focuses on deployment environment: "Will the system primarily be accessed through local devices within a secure network, or does it need to support remote access via the internet?" This guides analysts toward choosing between on-premises infrastructure and cloud-based or hybrid solutions.

Scenario Analysis

Let us consider a retail company planning to develop an integrated inventory and sales management system. Different responses to these questions lead to distinct architectural choices. In Scenario A, the company anticipates rapid growth, with plans to expand operations to multiple regions within a few years. The analyst’s response to the first question indicates a need for a highly scalable system. Consequently, the architect might favor a microservices-based cloud deployment, enabling independent scaling of modules such as inventory, sales, and customer management. For the second question, the system's operations require real-time updates on stock levels and sales transactions across all stores to prevent stockouts or overstocking. Hence, real-time processing architecture is selected over batch processing. Lastly, since the company’s staff collaborates across various locations and remote access is vital, a cloud-based deployment supporting secure remote access is preferred.

In contrast, Scenario B assumes the company is a small local retailer with limited growth prospects, primarily serving a single community store. The analyst’s response to the first question suggests that a simple monolithic architecture hosted on local servers suffices, with minimal scalability concerns. For the second question, batch processing may be adequate, such as daily inventory updates, as real-time accuracy is less critical for this scale. Regarding deployment, since the store’s staff work primarily onsite, an on-premises system would be feasible, reducing costs associated with cloud services. These responses guide the design toward a more straightforward, less complex architecture tailored to the company's current needs, with potential for future upgrades if circumstances change.

Implications of Different Responses

The responses to these questions profoundly influence the system’s architecture, cost, complexity, and scalability. A high-growth scenario warrants investment in flexible, scalable architecture with more sophisticated infrastructure, likely increasing initial costs but supporting long-term expansion. Conversely, a small-scale system prioritizes simplicity and cost-effectiveness, which may become limiting if future growth occurs unexpectedly. The choice of real-time versus batch processing impacts user experience, operational efficiency, and technical complexity; real-time systems demand more robust infrastructure and ongoing maintenance. Deployment choices additionally affect security, accessibility, and cost, with cloud-based solutions offering advantages in remote access and disaster recovery, but potentially introducing concerns around data security and compliance.

Conclusion

In conclusion, the questions a systems analyst asks regarding scalability, processing requirements, and deployment environment are critical in shaping the architecture of a new business information system. Different responses to these questions result in divergent technical frameworks, influencing the system’s capability to meet organizational demands, future growth, and operational efficiency. A thorough understanding of organizational context and strategic goals is essential for making informed architectural decisions, ultimately impacting the success of the implemented system.
