Transforming Integration Infrastructure at University of Portsmouth: A Microsoft-First Strategy

Executive Summary 

The University of Portsmouth undertook a significant digital transformation project to replace their costly, underutilised legacy integration system with Microsoft's integration services. With 24,500 students and 4,600 staff relying on approximately 200 applications, the university partnered with Valorem Reply to streamline their integration processes, modernise their approach, and build internal capabilities. Despite challenges in organisational culture and skills transition, the project has successfully deployed 9 production integrations with 28 more in development, significantly reducing integration development time from 18 months to a targeted 6-8 weeks. 

Background 

The University of Portsmouth is a significant higher education institution with 24,500 students as end customers and 4,600 staff. Their digital infrastructure comprises more than 200 different applications supporting both learning/teaching and business operations. This complex ecosystem requires robust integration capabilities to function effectively and deliver services to the university community. 

Prior to this initiative, the university operated within a complex legacy environment of disjointed systems and point to point integrations meaning significant duplication, reactive development, and long development timescales. That twinned with a lack of documentation, significant knowledge gaps and lack of skills in the market led to a situation ripe for transformation. This complex legacy technological landscape mixed with people factors is very typical of most large higher education institutions.  

On creation of the Digital Transformation Plan back in 2020, a key area of focus was information management, data and insight in being able to improve our operations, reduce duplication and bring efficiencies. This was a key part in getting our data foundations right to really unlock the benefit. 

The Challenge 

When Vicky Gosling joined as Deputy Director of Library & Information Services for Digital Solutions & Delivery in 2024, she inherited an integration infrastructure beset with multiple critical issues: 

• An expensive and vastly underutilized premium integration platform (using only 5-10% of available functionality) 
• A chaotic "spaghetti mess" of 120-130 point-to-point integrations across numerous systems 
• Multiple undocumented legacy systems with knowledge gaps due to staff turnover 
• Inconsistent development approaches described as "hobbyist" - developers chose technologies based on personal preference rather than strategic fit 
• Extremely slow development cycles, with new integrations taking 18-24 months to complete 
• Prohibitively expensive licensing costs for their existing integration platform 
• Difficulty recruiting staff with skills in legacy technologies, forcing reliance on costly contractors 

These challenges were occurring as the university was implementing a new digital transformation strategy with a "Microsoft First" approach for business applications, making their existing integration infrastructure increasingly misaligned with their strategic direction. 

Additionally, with an internal software development and integration team with no skillsets within the Microsoft technology stack, change resistance was high, confidence was low and fear, emotion and panic were areas that needed to be overcome to enable the university to move forwards. 

The Solution 

To address these challenges, the university decided on a comprehensive approach to support the new solution: 

1. Strategic Partnership: They identified the need to partner with a Microsoft integration specialist, selecting Valorem Reply to provide expertise in architecture, design, and implementation. 
2. Technology Transformation: Replacing the legacy premium integration platform with Microsoft integration services aligned with their broader "Microsoft First" strategy for business applications. 
3. People-Focused Approach: Recognising that technology alone wouldn't solve their problems, they emphasized upskilling their team, introducing new ways of working, and facilitating knowledge transfer from their implementation partner. 
4. Process Modernisation: Implementing Agile methodologies, CI/CD pipelines, and automated testing to streamline operations and accelerate delivery timelines. 
5. Accelerated Adoption: Leveraging Valorem Reply's Quick Connect accelerator to rapidly establish foundations and begin the learning process with the new technology stack. 

The solution focused on getting the architecture and design right from the start, setting up new integration development principles and an architectural framework based on best practice. With focus on getting our canonical model right first, with principles of reuse and efficiency really drove things forward. Logic Apps also become the core technological approach to development to simplify workflows, scale workloads, ease of development with low-code designers and easily monitor our consumption. 

Implementation 

The implementation approach centred on a collaborative partnership model between the university's technical team and Valorem Reply. Key aspects of the implementation included: 

1. Hybrid Team Structure: Creating blended teams with university staff working directly alongside Valorem Reply developers, initially in more of a shadowing capacity (80% shadowing, 20% development work), gradually evolving toward a more balanced contribution model (50/50 or 60/40) as internal team capabilities developed. 
2. Agile Transformation: Introducing Agile methodologies to a team with no prior experience, including establishing new ceremonies, processes, and ways of working. 
3. Knowledge Transfer: Rather than relying on formal training before implementation, the team adopted a "learn by doing" approach with guided challenges and on-the-job skill development supported by Valorem Reply. 
4. Incremental Development: Taking a phased approach to interface migration, with a focus on establishing foundational capabilities before scaling up development efforts. 
5. Cultural Change Management: Addressing the significant mindset shift required for the technical integration team to embrace new technologies and methodologies simultaneously. 

The project has been running for nearly two years, with progress somewhat slower than initially anticipated due to the scale of organisational and cultural change required rather than technological challenges and really demonstrates the commitment required for true transformation. 

Results and Outcomes 

While the project is still in progress, several tangible outcomes are already evident: 

1. Integration Development: 9 production integrations, made up of 21 separate interfaces, have now been successfully deployed, with 28 more in progress and 40 still to be developed (and growing due to new systems and requirements). 
2. Team Capability: The technical integration team has shown significant progression in both technical skills and Agile ways of working, with growing confidence to take on more complex development tasks. 
3. Process Improvements: New development and testing processes, including automated testing, have been established, creating a foundation for more consistent and rapid delivery. 
4. Licensing Cost Savings: Moving away from the expensive legacy platform has begun to deliver cost benefits. The team is still adjusting to the consumption-based pricing model of cloud services however consumption is lower than initially expected. 
5. Development Efficiency: We are now seeing deployments every 2-3 months, down from 18-24 months and we are able to be more agile in responding to change. 

Lessons Learned 

Several key insights emerged from the university's experience: 

1. People-First Transformation: The project reinforced that technical transformations are fundamentally about people. Empowering the team through knowledge building and aligned development, as well as building confidence and trust through Agile ceremonies and being open to adapting was critical for success. 
2. Data Analysis as Parallel Backlog – Running data analysis as its own Agile backlog freed up development time to be able to pick up pace. Data analysis comes with its own challenges and needed its own focus and to run on a different schedule. 
3. Working in Partnership – Having a flexible, patient and knowledgeable partner that is culturally aligned with your university was key. The ability to have open conversations and truly work together as a team ensured success. 
4. Cultural Adaptation: The shift to consumption-based cloud services required adjustment within the university's rigid budget cycles and traditional funding models. 
5. Managing BAU – Balancing BAU support of the new integrations against an ever growing pipeline of new requests is a challenge that we needed to flex and adapt to, moving resource as required and ensuring enhancement whilst continuing  with the new. 

Benefits 

Several key insights emerged from the university's experience: 

1. Complexity Reduction: Reducing environment complexity from 120-130 integrations to 60-70 more standardized interfaces has simplified the architecture and will improve supportability. 
2. Future-Proofing: The new approach allows for system changes without requiring extensive rewrites, essential in a university environment where staffing changes can drive system preferences and change is near constant. 
3. Skills Availability: The Microsoft ecosystem provides better access to available talent compared to niche legacy technologies, improving long-term supportability. 

Conclusion 

The University of Portsmouth's integration transformation project demonstrates how higher education institutions can modernize their technical infrastructure while building internal capability. By focusing on both people and technology aspects of the transformation, they've created a foundation for more agile operations and faster deployment of new capabilities. 

The "Nirvana" of faster deployment that Vicky Gosling references will enable the university to be more responsive to changing needs and leverage the power of integrated data across their complex application landscape. While the journey is ongoing, the university has established a clear path toward a more sustainable, maintainable, and efficient integration environment that aligns with their broader digital strategy. 

This case illustrates that successful digital transformation in higher education requires patience with the pace of cultural change, investment in people alongside technology, and strategic partnerships to bridge capability gaps during the transition.
