Open APIs supporting Digital TransformationsThe digital revolution creates both significant opportunities and threats. Impacting every industry, service providers can embrace significant growth opportunities by looking beyond connectivity.

Drive digital business transformation through industry-wide collaboration, experimentation and innovation

▪ Independent association with global membership, reputation and impact

▪ Extensive collaborative expertise and capabilities, with deep experience in Operations & IT

▪ Large global community with experts from across the telecoms landscape

Reduced time to market

Business agility and interoperability

By supporting an architecture based on modularity and reuse where capabilities are exposed through industry agreed Open APIs

Partnering for new services

Enable new products and services to be created by providing services to, and consuming services from, other business units, subsidiaries and external 3rd parties from telco and increasingly other verticals

Simplification of the IT estate

By enabling systems rationalisation

By enabling the configuration and reconfiguration of systems and capabilities through Open APIs to deliver new business solutions

Introduction and background to Open APIs in the context of ODA

Benefits of Components within an overall ArchitectureLoose coupling enables you to build the components independently of each other

Supported by a standard means of communicating between components to minimise integration costs – API hub/ESB

Use a set of appropriate metrics to measure and track the progress of your transformation – API’s built, systems rationalised, cost reduced, time to market reduced, functionality delivered increased etc.

Develop a standard enterprise data model (based on SID) to enable frictionless data transfers between platforms and partners

Determine what your core business services are (Open API’s), and build them to support your standard business processes (eTOM)

Data drive your product definitions and rules to ensure your architecture remains service agnostic to enable the management of hybrid environments and simplify on-boarding of partners or expansion into adjacent ecosystems

ODA sub-divides the architecture into logical blocks or components to simplify the architecture, grouping related business functions into platforms and presents a transformation blueprint that enables architects and designers to approach their business problem in a structured way.

Introduction and background to Open API’s in the context of ODA

A single framework that sets the vision and tools for IT and operating model fit for the 5G era

ODA is is the TM Forum’s proposal to enable richer and yet open, distributed digital collaboration with the essential tools to support increasingly demanding technical and commercial models.Technology progress such as:- 5G, AI, software defined networks, network virtualisation, SaaS (cloud ready, cloud native applications) are all driving OSS/BSS changes to simplify, automate and embed intelligence into the architecture.

ODA, through Components and Open APIs, provides:

Business agility

Lower cost of operations

Eco-system capable services

Multi-vendor support

Support for flexible business models

Ability to exploit the flexibility of the cloud

Digital efficiency – Analyze your processes, products and customers using business capabilities. Deconstruct your business using standard patterns – identify duplication, inefficiencies, common requirements. Build solutions to use common services that drivere-use, optimize and simplify processes, rationalize systems enable rapid change through model, rule and data driven capabilitiesDigital enablement – Identify which eco-system(s) you want to participate in and expose your services accordingly, using Open API’s to maintain loose coupling, tight integration and simplify partnership integrationObservation – The more mature and ubiquitous Digital Efficiency is throughout your organization, the easier it will be to deliver Digital Enablement

Open APIs support Digital Efficiency

Transform your IT estate to components and Open APIs

• Identify the components of your architecture and identify (using the ODA blueprint) the business functions, expressed as Open APIs that you wish to develop over time.

• Build a roadmap for the development of your critical business functions that facilitate digital efficiency.

• Identify duplication, inefficiencies in processes and common functions that are needed and build these in prioritized order.

• Ensure your delivery processes are ready to build common services

• Build the required Open APIs (please feedback improvements)

• Digital transformation is not just about IT, it also impacts:

– Operations

– Strategy

– Customers

Open APIs support Digital Enablement

Digital Transformation takes time and needs to be carefully managed

• Using your platform based architecture identify the target solution that you want to implement, expressed in terms of components and capabilities exposed as Open APIs

• You can use “pace layering” to identify areas of innovation and areas of differentiation that you wish to introduce into your architecture – these can be your areas of priority for development

• Build your new component functionality, following the ODA patterns, and ensuring that the Open APIs can carry the relevant product or service payloads

• Identify which Open APIs you wish to expose to partners and 3rd parties to enable them to consume your business services

• Work with your partners and suppliers and get them to adopt the Open APIs so that you can easily consume their services into your processes and functions
