During the past three decades in change, decision-making has become noticeably more complex. Prior to matrix management structures and agile ways of working, decisions were made functionally and were more top-down. Now, decisions are likely to be more democratic, involving a larger number of stakeholders.
Every choice can have significant implications on workplace, social, environmental, and economic fronts. This is where impact assessments come into play. They help the broad array of stakeholders in organisations and government understand the potential outcomes of their actions. By analysing the effects of changes and decisions before they are made, impact assessments ensure better outcomes for the organisation and the change community.
The Importance of Impact Assessment
When organisations embark on a new project, they often face the daunting task of predicting the future. What will the effects be? Who will be impacted? These questions can be difficult to answer without a solid foundation of data and analysis.

Impact assessments serve as the bedrock of informed decision-making during change. They help stakeholders identify potential risks and benefits, ensuring a comprehensive understanding of the implications of a project. By examining a range of relevant factors, these assessments bring clarity to complex decisions.
Impact assessments are crucial for various reasons:
Identifying Risks and Opportunities: By gaining insight into the potential positive and negative consequences of a project on the people impacted by it, organisations can proactively address challenges and seize opportunities.
Enhancing Communication: An effective impact assessment provides a common language for stakeholders, aiding in discussions about project specifics and downstream impacts.
Improving Compliance and Accountability: Many industries face stringent regulations that require impact assessments. Conducting these assessments helps organisations stay compliant. They also enable accountability by identifying the key personnel to be involved in mitigating impacts through subsequent change management planning.
Benefits of Conducting an Impact Assessment
In terms of change management techniques, the humble change impact assessment can polarise opinions. Some change managers believe the detailed work required to conduct effective assessments isn’t worth the results, while others would argue that without this detailed work, designing targeted change interventions becomes nigh impossible.
Organisations that prioritise impact assessments enjoy numerous benefits. They not only minimise risks, enhance collaboration, and build support for the change management effort, but they also pave the way for sustainable growth. Here are a few key advantages:
Better Resource Allocation: Impact assessments allow organisations to understand the impacts of change and allocate resources more effectively. Knowing the potential impacts lets them invest time and money where they'll create the most value.
Enhanced Public Trust: When organisations demonstrate a commitment to understanding the consequences of their actions, they build trust with stakeholders, employees, and the community. Transparency is key to maintaining positive relationships.
Informed Strategic Planning: Conducting an impact assessment provides data and insights that can inform long-term strategic planning. Organisations can make choices aligned with their vision while minimising adverse effects. In addition, the data collated in regular impact assessments can support change teams in their campaigns to move towards effective portfolio change management.
What is the impact assessment process?
The impact assessment process typically involves several stages, each designed to ensure that various factors are appropriately examined. While the exact structure may vary by practitioner and industry, a general framework includes:
Identifying stakeholders: Determining who is impacted by a particular project.
Current and Future State: Defining the current way each impacted group is operating, and how that will vary as a result of the change.
Assessment: Analysing the differences and isolating potential impacts, incorporating data collection, stakeholder engagement, and research.
Strategies: Documenting findings and recommendations in a clear, accessible format for subsequent development of tailored action plans.
Action and Readiness Monitoring: After design and implementation of appropriate change interventions, ongoing monitoring determines the actual impacts, allowing adjustment of strategies if needed.
By following a structured approach, organisations can ensure thorough evaluations that take various factors into account, leading to informed decisions.

Beyond Technology Delivery: Examples of Impact Assessment in Action
While technology delivery projects will be relatively familiar with change impact assessments, their potential is much greater. To understand further practical implications of impact assessments, consider these real-world examples:
Infrastructure Development: In urban planning, an impact assessment can reveal how a new highway might affect local communities. If a project displaces residents, mitigation strategies can be developed to address this issue, such as providing alternative housing options or enhancing public transportation.
Environmental Protection: Suppose a company wants to build a factory near a wetland. An environmental impact assessment can identify potential risks to local wildlife and ecosystems. Using these insights, organisations can make adjustments or choose alternative locations that minimise ecological and reputational damage.
Health Impacts: Public health officials often conduct impact assessments for new healthcare policies or programs. For instance, a new vaccination program might be evaluated for its potential effects on community health outcomes, helping policymakers make informed decisions based on the predicted effectiveness and public acceptance.
Steps to Implementing Effective Impact Assessments
For organisations looking to enhance their decision-making through impact assessments, here are actionable recommendations:
Engage Stakeholders Early: Involve affected parties early in the process to gather diverse perspectives. This leads to richer insights and helps build trust.
Leverage Data: Use existing studies and data to inform assessments. Partnering with subject matter experts—such as technology engineers, business people, scientists, or researchers—can provide valuable insights that may not be readily available.
Communicate Findings Clearly: Communications should be targeted to the impacts identified, making them accessible and understandable to all stakeholders, not just experts in the field. Visualisation tools, such as charts and infographics, can help convey complex information effectively.
Establish Monitoring of Change Readiness Actions: Develop a plan to monitor the impacts after implementation of change plans. This not only allows organisations to gauge the effectiveness of their strategies but also provides learnings for future projects.
Adapt and Evolve: Use feedback and monitored outcomes to refine the impact assessment process. Continuous improvement leads to better decision-making in future projects.
The Future of Impact Assessments
As our industry grapples with new technologies, complex workplace and environmental issues, the importance of change impact assessments will only grow. Practitioners and organisations that embrace this practice will be better equipped to create effective strategies for change implementations and make decisions that benefit the organisation as intended.
The continued evolution of technology will also enhance the impact assessment process. With big data analytics, artificial intelligence, and advanced modelling techniques, organisations will have more tools to predict and quantify potential impacts. The future of impact assessments looks promising, with a focus on sustainability and ethical decision-making.
In conclusion, embracing impact assessments is not just a tick-in-a-box; it is a strategic advantage. By understanding their importance and implementing effective impact assessment processes, change professionals can better support the organisations, communities, and environments they touch.
