Improvement Sustainability Model for Long‑Term Project Success
Here at EnterpriseIS, we believe that delivering excellence in every project is the function of successfully addressing the key areas that impact project sustainability to ensure long-lasting benefits.
We developed the Improvement Sustainability model to illustrate how these elements inter-relate and how they are addressed to deliver value throughout a project lifecycle.
What Is the Improvement Sustainability Model?
The Improvement Sustainability Model is a structured approach to achieving sustainable project outcomes. It focuses on three interconnected elements that together create long‑term success:
- Acceptance Strategy – securing stakeholder buy‑in and aligning organisational culture.
- Capability Building – equipping teams with the skills and knowledge to sustain improvements.
- Technical Solution Development – designing and implementing systems that support ongoing performance.
Three Core Elements of Sustainability
Acceptance Strategy
First is the Acceptance Strategy. Without buy-in from the people, no project can be successfully delivered. An Acceptance Strategy requires a complete understanding of the stakeholders impacted by the change, or stakeholders who can impact the change. This doesn’t mean that all stakeholders have to be experts in the technical components of the project, but it does mean they have to understand the objective of the project and what it intends to deliver, to ensure they support the implementation.
In order to develop acceptance in the project, EnterpriseIS utilises a range of change management tools, specifically to identify behavioural drivers and opposing barriers. By using these tools; process mastery, team autonomy and individual purpose for the project can be achieved, ultimately creating a complete sense of ownership in the project.
Capability Building
Capability Building is the next critical building block in the delivery of sustainable improvements. Understanding the capability of the stakeholders enables critical decisions to be made for the development of a highly effective workforce. Ensuring that the right people are in the right roles, having the right skills with the right competencies is what it takes to support a capable organisation.
Whether it’s addressing the organisation design, or completing additional coaching to enable the effective use of new tools and/or processes, building capability is more that just sending someone on a 3-day course. Building capability is about setting up the organisation to sustain the changes on an on going basis.
Technical Solution Development
Finally Technical Solution Development is the last piece in the puzzle for sustainable improvement. Developing the technical solution first starts with defining what you want to address and what success looks like, as this will drive the development of the correct scope. Once this is complete, we then establish an effective baseline to measure progress. Then can we start analysing the available data and identifying potential solutions.
Throughout this process, it’s imperative that stakeholder engagement is maintained to ensure the solution developed is relevant and able to be implemented in a cost/time effective manner. Finally, once the implementation is complete, measuring and monitoring the performance of the change is critical for closing the improvement loop and delivering a return on the investment.
