BSA/385 Week 1 Discussion Software Process and Requirement Analysis Changing Requirements in Software Process Write a 100- to 200-word response to the following: 1 • It is mentioned that "Clients often lack appreciation for the complexities inherent in software engineering, particularly regarding the impact of changing requirements." Imagine you are in this situation, what would you do to handle this situation, using knowledge you have learned in software process? Quality Procedures Write a 100- to 200-word response to the following question: 2 Explain why it is important to document quality procedures at the beginning of a project rather than later on. In addition, think about 2 advantages and 2 disadvantages of using standards for documentation in each of the software phases.

Software Engineering: Modern Approaches Write a 100- to 200-word response to the following questions: 3 Give an example of a software application in which the customer is the same as the end user. Give an example in which they are different. In each case, identify the customer and end user. Write a 100- to 200-word response to the following question: 4 What are three major advantages and disadvantages of describing detailed requirements with unit tests? 5 Explain why a defective requirement could be 100 times more expensive to fix after software is deployed versus being fixed during requirements analysis. 6 Give two advantages and two disadvantages to using standards for documentation of the `various software phases. 7 List four of what you consider to be the most important high-level requirements for an application that tracks bar-coded invoices within a company. 8 Describe in your own words the difference between customer wants and customer needs. Provide an example that illustrates the difference.

The complexities of software engineering and the mutable nature of requirements often create significant challenges for both developers and clients. When clients underestimate these intricacies, especially regarding evolving requirements, it becomes crucial to establish transparent communication and education strategies. As a software engineer, I would implement educational sessions early in the project lifecycle, emphasizing the unpredictability of requirements and the need for flexible processes like Agile methodologies. By clearly illustrating the cost implications of late changes and the importance of stable requirements upfront, clients are more likely to appreciate the necessity of comprehensive initial documentation and ongoing collaboration. Additionally, I would promote the use of prototyping and continuous feedback to mitigate misunderstandings and accommodate changes effectively. This approach aligns with best practices in the software process, ensuring that clients recognize the impact of requirement changes while fostering a cooperative environment that minimizes costly revisions later in development.

Documenting quality procedures at the beginning of a project is critical because it provides a clear framework for maintaining standards, ensures consistency, and facilitates effective communication among team members. Early documentation helps prevent misunderstandings and rectifies potential issues proactively, saving time and resources. It also creates a reference point for ongoing quality assurance activities. Regarding documentation standards, two advantages include improved clarity and consistency, which streamline project phases and improve stakeholder communication. Conversely, disadvantages include potential rigidity that may hinder flexibility and the risk of over-standardization, which could stifle innovation or lead to excessive bureaucratic overhead during development phases.

In software applications, a common example where the customer and end user are the same is a mobile banking app—where the bank (customer) directly uses the app, and the customers (end users) are individuals accessing their accounts. Conversely, in a hospital management system, the hospital administration (customer) commissions the system, but the doctors and nurses (end users) operate it daily for patient care. Recognizing these roles helps tailor requirements appropriately, ensuring the needs of the actual users and stakeholders are effectively met.

Describing detailed requirements with unit tests offers three advantages: early validation of code, clear understanding of expected behaviors, and improved documentation. However, disadvantages include increased initial effort to write comprehensive tests, and the risk that tests may become outdated if requirements evolve without updates, leading to false security or incomplete coverage. Such detailed testing can refine development but may also increase complexity and time before deployment.

A defective requirement can be significantly more costly if identified after deployment because it might necessitate extensive redesign, retraining, and reimplementation, affecting end-user satisfaction and operational costs. During requirements analysis, errors are more manageable and less expensive to correct—akin to fixing a typo in a document—whereas post-deployment fixes can involve hardware changes, re-certification, and significant disruptions that exponentially increase costs.

Using standards for documentation across software phases offers advantages like improved clarity and facilitating stakeholder understanding, which streamlines development and testing processes. Disadvantages include potential inflexibility, which may hinder customization or adaptation to unique project needs, and the risk of bureaucratic overhead that might slow down rapid development or innovation efforts.

Key high-level requirements for an invoice tracking application could include: 1) barcode integration for each invoice, 2) real-time inventory updates, 3) user authentication and access control, and 4) comprehensive audit logging for compliance and troubleshooting. These requirements ensure the system functions reliably, securely, and aligns with business operations.

Customer wants are desires or preferences, such as wanting a modern website design. Customer needs are essential requirements, like needing secure login capabilities for data protection. For example, a customer might want a feature-rich mobile app (want), but they need the app to be secure and easy to use (need) to protect sensitive information and ensure usability.
