The following is the result of a survey question posed by TM Forum:
I’m not sure how the numbers tally, but conceptually the graph above paints an interesting perspective of why orchestration is important. The graph indicates the why.
But in this case, for me, the why is the by-product of the how. The main attraction of orchestration models is in how we can achieve modularity. All of the business outcomes mentioned in the graph above will only be achievable as a result of modularity.
Put another way, rather than having the integration spaghetti of an “old-school” OSS / BSS stack, orchestration (and orchestration plans) potentially provides the ability to provide clearer demarcation and abstraction all the way from product design down into transactions that hit the network… not to mention the meet-in-the-middle points between business units.
Demarcation points support catalog items (perhaps as APIs / microservices with published contracts), allowing building-block design of products rather than involvement of (and disputes between) business units all down the line of product design. This facilitates the speed (34%) and services on demand (28%) objectives stated in the graph.
But I used the term “old-school” with intent above. The modularity mentioned above was already achieved in some older OSS too. The ability to carve up, sequence, prioritise and re-construct a stream of service orders was already achievable by some provisioning + workflow engines of the past.
The business outcomes remain the same now as they were then, but perhaps orchestration takes it to the next level.
Standing out in a highly saturated and fragmented OSS market can be really difficult. We’re regularly involved in bake-offs where we see dozens of OSS
One of the things I love about my job is all the vendor demos I get to see. Product demos are one of the four
Have you read the book, “The 4-hour work week” by Tim Ferris? It was one of those relatively rare books that inspired a complete mindset
Over the years, we’ve been involved in many OSS procurement events and have seen a variety of different pricing models proposed by vendors. Being software,
