Adoption Assessment Survey Q4 2020 results

37 vendors and 10 communication service providers (CSP) participated in the V3a (Q4 2020) Open API adoption assessment survey, a 57% increase on the V2 survey published a year ago (November 2019).

The results show significant industry momentum towards Open API adoption, with the overall level of intent (combined scores for CSPs and vendors) increasing by 12 percentage points since the V2 survey.

We are also seeing increasing maturity of Open API deployments with vendor maturity increasing by 8 percentage points. Vendors appear to be responding to CSP demand, with several moving into the top right quadrant.

CSP Maturity remains, on average, higher than the vendors, but results are skewed by the leaders wrapping their legacy APIs as a placeholder pending native support in vendors’ products. Lester Thomas, Chief IT Systems Architect, Vodafone Group, confirmed this trend. “The majority of our Open API implementations to date have been wrapping our product vendors’ legacy APIs.  This is partly driven from the fact that we are building a digital experience layer across all our markets while we are modernizing the back-end vendor systems-of-record at a slower rate,” he said.  “We have started to see native TM Forum Open API implementations from some of our vendors, and all of the new BSS implementations we have done over the last two years have included native support for TM Forum’s Open APIs.”

CSP demand outstrips supply, creating opportunity for vendors to serve those with high ambition, with average CSP intent much higher than average vendor maturity, while leading CSPs also need native Open API support from their vendors in order to replace their DIY wrappers.

CSP and vendor prioritization of API collections are well aligned, although CSPs have a somewhat wider focus.
