Creation of an integrated ecosystem using APIs
for a UK Telco major
As a first step, an API Governance Team was constituted to frame the appropriate guidelines, standards and to define the roadmap for the API Management Program. An “API Farm” team was then setup by the operator in collaboration with THBS, for better management and monetization of APIs. The API Governance team structure is as below:
The Governance materials drafted as part of initiation and ongoing phases of the API management program along with the artefacts required during the different phases of the API lifecycle are captured below:
THBS adopted a “Factory Model” to create, develop, test and deliver APIs at scale – based on the guidelines from the Governance team. The Factory model ensures consistency in delivery and predictability in-terms of timelines and costs. It runs on the principles of an Agile model, specifically - the Scrum methodology. Estimations are done based on the T-Shirt sizing model (small, medium, large and Extra-large), based on the complexity of the functionality involved.
The THBS API Factory team worked with several critical programs and cross-functional teams as part of API Management Delivery. Delivering 50 plus APIs for the Self-Service Mobile Application within a 6-month period was one of the highlights of this collaboration.
Spurred by the successful delivery of the initial APIs, this initiative was further expanded within the client enterprise as part of the newly formed Digital Transformation Strategy. There was a mandate to use a common integration layer across the business, to ensure that all subsidiaries / CFUs maximise reuse and gain benefits through cross-CFU usage.
