Delivering a data-driven mobile application under tight deadlines using a sprint-based delivery model

Client

A large, complex enterprise organisation undergoing cloud migration, with fragmented data across legacy and modern systems.

The Challenge

The client needed to deliver a data-driven mobile application within a fixed deadline, enabling frontline teams to access performance metrics in real time.

The scope required multiple capabilities:

• Data engineering and pipeline development
• iOS application development
• UX and user-led design
• Security, governance, and compliance

Internally, these capabilities were fragmented. The initial approach was to hire a single contractor, but the scope required multiple specialist skillsets working in coordination.

This created delivery risk against the deadline, with added complexity from:

• Hundreds of metrics across multiple systems
• Data split across legacy platforms and cloud environments
• Strict security and access requirements for sensitive data
• Ongoing cloud migration affecting how data could be accessed and structured

The Rockborne Solution

Rockborne moved the engagement from resourcing to end-to-end delivery ownership, introducing a fixed-price, sprint-based delivery model to reduce risk and accelerate progress.

This model allowed delivery to start early, with scope refined as the project progressed.

We delivered:

• Cross-functional delivery team spanning data engineering, application development, and product design
• Sprint-based model with 4-week milestones, allowing flexible prioritisation and regular sign-off
• Data engineering to consolidate hundreds of metrics into a single, usable data layer
• iOS application development, built alongside the data to ensure a consistent user experience
• User-led design and testing, working directly with end users to ensure usability and adoption
• Security and governance built into delivery, including access control, compliance, and documentation

Results

Rockborne delivered a fully functioning data-driven mobile application within the required timeframe and budget. The application enables frontline users to access key metrics in real time and act on them.

Despite a complex environment of legacy systems, ongoing cloud migration, and strict governance requirements, the team successfully consolidated data, validated accuracy through continuous testing, and met security and compliance standards throughout delivery.

User adoption was driven by ongoing testing and iterative design, ensuring the application reflected real user behaviour and needs.

The success of the initial delivery has already led to further development phases, demonstrating a repeatable model that can be applied across similar use cases and industries.

• End-to-end iOS application delivered
• Hundreds of metrics consolidated and engineered
• Multiple data sources across legacy + cloud environments
• Sprint-based delivery with 4-week milestones
• Delivered on time and within budget
• Continuous user testing with real end users
