Interface modeling is a technique to describe how different components or systems interact with each other and exchange information. Interface modeling can be used to depict how the solution will work with all of the company’s systems by showing the inputs, outputs, and dependencies of each system. Interface modeling can help to identify potential integration issues, gaps, and conflicts among the systems. The other techniques are not suitable for this purpose. Data modeling is a technique to define the structure, format, and relationships of data. Rules modeling is a technique to define the logic, constraints, and policies that govern the behavior of the solution. Enterprise modeling is a technique to describe the structure, culture, and processes of an organization. References: PMI-PBA® Examination Content Outline, page 11; PMI-PBA® Reference List, page 1, BABOK® Guide v3, page 54.

 Quality function deployment (QFD) is a technique that involves translating customer needs or requirements into product features or specifications. QFD helps to relate the product features to customer value by using a matrix called a House of Quality, which shows how each feature satisfies a customer requirement, how important each requirement is to the customer, how well each feature performs compared to competitors, and how each feature affects other features. QFD can also help to identify gaps or opportunities for improvement in the product design. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline (2019), page 12; Business Analysis for Practitioners: A Practice Guide (2015), page 69.

Requesting information on the current ordering process and comparing it with other companies is a technique that involves gathering data and benchmarking best practices from similar or relevant sources. Requesting information on the current ordering process and comparing it with other companies can help the business analyst to take the next step after completing the requirements by analyzing the current state of the problem, identifying gaps or opportunities for improvement, and proposing possible solutions or alternatives. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline (2019), page 12; Business Analysis for Practitioners: A Practice Guide (2015), page 69.

 MoSCoW is a requirements prioritization method that classifies requirements into four categories: Must have, Should have, Could have, and Won’t have. This method helps the business analyst and the stakeholders to agree on the essential requirements that must be delivered within a fixed time frame, and the desirable requirements that can be deferred or dropped if necessary. MoSCoW is suitable for this project because it allows the business analyst to focus on the minimum viable product that meets the business need of replacing the current enrollment and billing software application before the vendor contract ends, and to cope with the large volume of requirements by prioritizing them based on their value and urgency. References: PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline1, page 18; Business Analysis for Practitioners: A Practice Guide2, page 92.

 The MoSCoW technique is a prioritization technique that helps to rank requirements according to their importance and urgency. The acronym stands for Must have, Should have, Could have, and Won’t have. This technique can help the business analyst to manage requirements by focusing on the most critical ones and minimizing the scope creep. References: = PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline, page 19.

The main reason for the business failure was a failure to establish measurable success criteria in the business case. The success criteria are the standards or indicators that are used to measure the achievement of the business objectives and the expected benefits of the project. The success criteria should be defined and agreed upon by the stakeholders in the business case, and they should be specific, measurable, achievable, realistic, and time-bound (SMART). The success criteria can help the business analyst and the project team to evaluate the feasibility, viability, and desirability of the project, and to monitor and control the project performance and outcomes. The success criteria can also help to ensure the alignment of the project deliverables with the stakeholder expectations and the market needs. If the success criteria are not established or are poorly defined in the business case, the project may fail to deliver the desired value and return on investment, even if it meets the time, cost, scope, and quality constraints. References: PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline1, page 16; Business Analysis for Practitioners: A Practice Guide2, page 86.
