Managing solution scope is the task of ensuring that the solution meets the agreed-upon requirements and delivers the expected value to the stakeholders. Managing solution scope involves analyzing the impact of any changes to the scope, assessing the feasibility and risks of the changes, and obtaining approval from the stakeholders before implementing the changes. Managing solution scope can help the business analyst to identify the impacts, dependencies, or risks associated with the addition to the scope.

A survey is a technique that involves collecting information from a large number of people by asking them questions and analyzing the results. Surveys are often used to measure the satisfaction, opinions, preferences, or attitudes of customers, employees, or other stakeholders. Surveys can be conducted through various methods, such as mail, online, phone, or in-person. Surveys are a suitable technique for gathering information from employees regarding their satisfaction with the solution because:
* Surveys can reach a large and geographically dispersed population of employees across the country.
* Surveys can allow employees to provide anonymous and honest feedback without being influenced by peer pressure or group dynamics.
* Surveys can use standardized and quantifiable questions that can be easily analyzed and compared.
* Surveys can be cost-effective and time-efficient compared to other techniques that require more resources and coordination.

According to the PMI Guide to Business Analysis, a use case is a technique that describes how an actor interacts with a system or a process to achieve a specific goal. A use case can help to prevent problems from occurring in the implementation of a new application, as it can capture the functional requirements and the expected behavior of the system or the process, as well as the exceptions and alternative flows. A use case can also help to design and execute test cases that cover all the possible scenarios and outcomes. In this case, a use case could have prevented the problem of a worker using a field that was not supposed to be used, as it could have specified the valid inputs and outputs for the report, and the actions and responses of the system or the process. Prototyping, diagrams, and document analysis are other techniques that can help to analyze and communicate requirements, but they do not necessarily prevent problems from occurring in the implementation of a new application, as they do not describe the interactions and outcomes of the system or the process in detail.

Value-ranking criteria are a set of factors or measures that are used to evaluate and prioritize the value of backlog items. Value-ranking criteria can include business objectives, benefits, costs, risks, dependencies, urgency, etc. The stakeholders follow the value-ranking criteria to determine the value of backlog items based on their alignment with the project vision and goals. The stakeholders can also use techniques such as MoSCoW analysis or weighted ranking matrix to apply the value-ranking criteria.

A strategies and goals analysis is a technique that helps to ensure that the projects are aligned with the organization's vision, mission, values, and strategic objectives. A strategies and goals analysis helps to identify the business problems or opportunities that the projects are intended to address, and to evaluate the expected benefits and outcomes of the projects. A strategies and goals analysis also helps to prioritize and select the projects that have the highest potential to improve the company's performance and profitability.
