Strategic Applications Architecture Roadmap

Overview

The client is a regional transportation authority serving the St. Louis metropolitan area through public transit and related services. Supporting these operations requires a diverse application landscape that spans customer facing systems, operational platforms, data integrations, and internal tools.

As technology plays an increasingly important role in service delivery, they sought to better understand how its application portfolio could evolve to support reliability, scalability, and future innovation. The organization engaged Oakwood Systems Group to develop a strategic applications architecture roadmap that would assess current state systems, identify modernization opportunities, and define a clear path forward aligned with business and security priorities.

Business Challenge

The client faced challenges related to aging applications, integration complexity, and limited visibility into how systems aligned with long term organizational goals. Legacy platforms and custom integrations created friction for development teams and introduced risk related to maintainability, scalability, and security.

In addition, they needed to evaluate DevOps maturity, code management practices, and separation of duties across teams. Critical systems supporting transit operations and data exchange required careful consideration of security, compliance, and operational continuity. Without a unified view of the application landscape, it was difficult to prioritize modernization efforts or identify opportunities for early wins that could deliver measurable value.

Solution

Oakwood partnered with them to conduct a comprehensive evaluation of its application and integration landscape, with a focus on aligning technology capabilities to operational and strategic priorities. The engagement emphasized understanding how applications supported transit operations, customer facing services, data exchange, and internal workflows. Stakeholder interviews were conducted with system owners, architects, developers, and security leaders to surface technical constraints, operational challenges, and modernization goals.

Oakwood reviewed existing architecture documentation, integration workflows, and application dependencies to establish a clear current state view. Particular attention was given to legacy platforms, custom integrations, and data exchange patterns such as GTFS replication and external system interfaces. DevOps practices, source control usage, deployment processes, and separation of duties were assessed to identify opportunities for improved consistency, security, and delivery efficiency.

Security and risk considerations were incorporated throughout the engagement through close collaboration with the client’s security leadership. Authentication models, access controls, and governance practices were evaluated to ensure modernization recommendations aligned with regulatory requirements and operational continuity while supporting future scalability. Findings from the assessment were synthesized into executive ready deliverables, including current state and target state architecture views, a prioritized list of modernization initiatives, and a capability improvement roadmap.

Outcome

The engagement provided the client with a clear, actionable modernization roadmap grounded in its operational and technical realities. Leadership gained improved visibility into the current application landscape and a structured understanding of where modernization efforts would deliver the greatest impact.

The roadmap established prioritized initiatives aligned to business risk, technical opportunity, and organizational readiness. Clear architecture views and capability recommendations helped align stakeholders across technology, security, and operations. With a defined strategy and recommended pilot effort in place, they were positioned to move forward with modernization initiatives in a more deliberate, coordinated, and confident manner.
