This is because a business case is a document that provides the justification and rationale for initiating, continuing, or terminating a project or program. It describes the business problem or opportunity, the objectives and benefits, the costs and risks, the alternatives and assumptions, and the expected outcomes and value of the proposed solution. A business case is not a static document, but rather a dynamic one that should be updated throughout the life cycle of the project or program, as new information, changes, and feedback emerge. Updating the business case throughout its life cycle can help to ensure that the project or program remains aligned with the business strategy and goals, as well as to monitor and evaluate its performance and value delivery.

Some of the sources that support this answer are:

1: This source provides a comprehensive guide on how to write a business case, including its purpose, structure, content, and format. It also explains why it is important to update the business case throughout the project or program life cycle, as it can help to track progress, measure benefits, manage risks, and communicate results.

2: This source discusses the benefits and challenges of updating the business case during the project or program execution. It suggests that updating the business case can help to validate assumptions, verify feasibility, adjust scope, and justify changes. It also provides some tips and best practices for updating the business case effectively and efficiently.

3: This source defines what a business case is and how it can be used to support IT governance and decision-making. It states that a business case should be updated regularly throughout the project or program life cycle, as it can help to ensure alignment with the enterprise architecture (EA), assess risks and opportunities, and demonstrate value realization.

 Engaging stakeholders to identify and validate business requirements is the best way to improve the success rate of future IT initiatives. Stakeholders are the individuals or groups who have an interest or influence in the IT initiatives, such as business users, customers, managers, sponsors, etc. Engaging stakeholders can help:

Understand the needs, expectations, and priorities of the stakeholders, and ensure that they are aligned with the business objectives and strategy

Define and document the business requirements that specify what the IT initiatives should deliver in terms of functionality, quality, performance, and value

Validate and verify that the business requirements are clear, complete, consistent, feasible, and testable

Communicate and manage any changes or issues that may affect the business requirements or the IT initiatives

Engaging stakeholders to identify and validate business requirements can help avoid missing key functionality in the corporate applications, and ensure that they meet the stakeholder’s needs and expectations. This can also reduce the reliance on spreadsheets and databases as alternative software solutions, and increase the user satisfaction and adoption of the enterprise applications.

The other options are not the best way to improve the success rate of future IT initiatives. Engaging the business user community in acceptance testing of acquired applications is a good practice, but it is not sufficient to ensure that the applications have the key functionality that meets the business requirements. Acceptance testing is done at the end of the IT initiative lifecycle, after the applications have been developed or acquired. If the business requirements were not properly identified and validated at the beginning of the IT initiative lifecycle, acceptance testing may reveal significant gaps or defects that may be costly or difficult to fix. Establishing a process for risk and value management is a useful technique, but it does not directly address the issue of missing key functionality in the corporate applications. Risk and value management involves identifying, assessing, prioritizing, and treating the risks and benefits associated with IT initiatives. However, without clear and valid business requirements, risk and value management may not be effective or accurate. Prohibiting the use of non-approved alternate software solutions is a restrictive measure, but it does not solve the problem of missing key functionality in the corporate applications. Prohibiting the use of spreadsheets and databases may force the users to use the enterprise applications, but it may also create dissatisfaction, frustration, or resistance among them. Moreover, it may prevent them from performing their tasks efficiently or effectively if the enterprise applications do not meet their needs.

Collaborative tools and approachesenable integrated reporting, real-time data collection, and cross-functional analysis, which are crucial for measuring complex ESG metrics. These tools foster participation from different departments (HR, compliance, sustainability) and ensure that insights are holistic and timely.

While audit oversight provides governance validation and benchmarking offers external comparison,collaborative systems facilitate the ongoing operational visibility needed to manage ESG performance proactively.

When a regulatory change significantly affects an ongoing project, thefirst step should be to perform an impact analysis and update the business case.This helps the organization understand how the change influences cost, timelines, compliance, and value delivery.

Only after understanding the impact should actions such as seeking reapproval, changing scope, or applying for exemptions be considered. This aligns with the principle of informed decision-making in IT governance.
