An overlay architecture makes the most of legacy systems and mature landscapes and provides single integrated processes and data view over existing independent stacks to all channels.
Celfocus Digital Overlay Architecture
As business is constantly evolving, IT architectures’ responsiveness to change must be improved to be more flexible by design. While current systems may still be able to improve the overall effectiveness and increase the available capabilities, they struggle to provide the foundations for organizations to efficiently respond to new demands and competitors’ challenges in the digital economy. An evolutionary IT architecture enables incremental changes over time, in a non-disruptive fashion, to support the preparation for the fast and exponentially growing demands and needs of the future, whilst relying on innovative and scalable overlay frameworks with self-contained capabilities. An overlay architecture makes the most of legacy systems and mature landscapes and provides single integrated processes and data view over existing independent stacks to all channels. It also allows the deployment of basilar foundations, providing a transient evolutionary path to support next-generation service delivery and deliver fit-for-purpose business insight leveraged on big data and machine learning technologies, while driving the architecture to a fully digital state.
Celfocus Digital Overlay Architecture (DOA) is the first step towards full digital embracement, consisting of a phased approach that paves the way to the migration from legacy to full digital architecture, introducing or moving the required functions and functional domains.
It lays the groundwork for IT requirements and allows the overall architecture to address the pain-points observed in legacy architectures and to make the fundamental shift towards new paradigms. This shift is supported by five pillars, which together create and promote a matrix of capabilities required to support the needs of modern digital companies while introducing a common vision for available offerings and processes. They also allow the necessary architectural principles to be defined.
Celfocus DOA overview introduces a Digital Platform composed of three main layers and three cross-cutting blocks.
Digital Exposure Layer:
driven by experience, this layer exposes information that is meaningful to consumers, acting as a gatekeeper of the internal organization systems. It also exposes APIs to outside parties, facilitating the partnership with digital ecosystems and setting the rules for interfacing with the underlying systems and ensuring security policies.
Digital Process Layer:
managing process orchestration and related business logic abstracted from the underlying supporting systems, this layer supports a seamless and consistent cross-channel experience and a faster launch of new customer journeys and/or business processes.
Digital Resources Layer:
driven by resources, this layer manages the lifecycle of processes and resources and ensures the virtualization of data records and underlying logic (self-contained or from legacy systems), abstracting its access and specificities to the Process Layer.
Integration:
manages and ensures the separation of functional borders, guaranteeing that services provided by each component can be combined flexibly. It facilitates and promotes componentisation and decoupling principles by ensuring communication between components.
Enterprise:
consolidates data using a common model to create a customer single view, simplifying the overall architecture and data synchronization processes. It’s responsible for granting access to data and information by all users and systems in near real-time; for making dedicated digital data available to support user experience; and for managing and supporting digital content creation and modification.
Analytics:
consolidates capabilities aimed at supporting and improving customer experience through the consumption, collection and analysis of data (from network to customer experience), to develop insights for decision support, intent-based actions or advice.
Celfocus DOA supports an evolutionary approach to serving the business iteratively, allowing success to be measured during the whole process and the strategy to be adjusted accordingly.
Digital Transformation entails changes that should be embraced gradually. An important step is to upgrade to an IT architecture that sets the foundations for a full digital embracement. Celfocus DOA is the cornerstone to support an architecture that fits in with modern paradigms of adaptability and evolvability. In perfect consonance with TM Forum’s Open Digital Architecture (ODA) blueprint, it supports the incremental delivery of the digital capabilities that enable the new platform model envisioned for the telco market.
