Explain The Issues Illustrated Byeachpicture And Its Caption In The Co

Explain the issues illustrated by each picture and its caption in the context of project failures in regards to systems analysis. Draw your Activity Diagram on this page: Activity Diagram Our chain of pharmacies is considering implementing a self-service checkout system, called SelfCheck in order to reduce the staff required to man the cash registers. With the resources freed up by the automated checkouts, our goal is to add more pharmacy technicians to improve satisfaction with the prescription-filling process. One use case of the SelfCheck system is named “Scan Membership Card”. Our pharmacies have a customer loyalty program that uses the little keychain cards like many grocery stores.

SelfCheck is built to handle this and a customer may scan their membership card to tell the system to invoke membership benefits and discounts. They will receive the same membership benefits as checking out as they would at a regular register. On the following page, draw an activity diagram with swimlanes (partitions) to model the “Scan Membership Card” use case steps described below:

Scan Membership Card Activities: The customer scans their membership card over the Selfcheck barcode reader. Selfcheck validates that the barcode was swiped correctly. If unsuccessful, Selfcheck displays an error message and then the use case is done.

If successful, Selfcheck will search for the customer’s identification number. If not found, SelfCheck displays an error message and then the use case is done. If the customer identification number is found, the next two activities can be performed simultaneously. SelfCheck will apply discounts to already scanned items, while at the same time setting a discount flag to make sure that goods scanned in the future also receive a discount, if applicable. Once these two activities are done, Selfcheck will display a discounts applied message and then the use case is done.

The provided images and captions in the context of project failures in systems analysis often illustrate common pitfalls such as inadequate requirement gathering, poor communication among stakeholders, insufficient testing, or flawed system design. Without seeing the actual pictures, it can be inferred that they likely depict scenarios like failed implementation, user interface issues, data accuracy problems, or integration failures, which are typical in system development projects. These failures commonly stem from a lack of clear understanding of user needs, insufficient analysis, or poor planning during the system design phase.

In the case of the SelfCheck system for pharmacies, failures may arise if the system inaccurately validates barcodes, leading to customer frustration or errors in applying discounts. For example, if the barcode validation step is flawed, it could cause repeated error messages, thus affecting user satisfaction. Similarly, if the system cannot find customer's ID numbers due to database issues, it results in failed recognition of loyal customers, thereby reducing the effectiveness of the loyalty program and impacting customer retention.

Furthermore, simultaneous processes like applying discounts and setting discount flags should be carefully synchronized; failure in synchronization could lead to inconsistent discount application, which causes billing errors or customer dissatisfaction. The system's inability to handle these concurrent activities properly highlights issues in process modeling, concurrency management, and system robustness in systems analysis.

The activity diagram to model this use case should clearly depict the sequence of actions, decision points, and parallel activities. Proper use of swimlanes ensures clarity in responsibilities across system components. Failure to accurately model these activities could result in misaligned development efforts, poor system performance, or integration issues, ultimately leading to project failure.

In conclusion, the issues illustrated by the pictures and their captions underscore the importance of thorough systems analysis, clear process modeling, rigorous validation, and testing in project success. Addressing these areas proactively during the development phases can mitigate risks and improve the likelihood of successful system implementation.
