I would have loved to estimate how much of this is contributed by Communication Service Providers (CSPs) alone but sadly I dont have any data with regards to that. But conservatively speaking it should be close to 50%. And my guess is 20%- 30% of that would be on IT software and services. CSPs would then spend 30% - 50% of their total IT software spend on BSS/OSS (including internal and external)...If the total spend on IT spend worldwide is $1.5tr then BSS/OSS market should be close to $40bn. Its a rough estimate but not should not be too far off. Sounds like a huge market and it is. Moreover BSS/OSS is the fastest growing space in the telecom software space. It feels as if this is the place to be in. Then why are we seeing so many companies in BSS/OSS space struggling and finding hard to survive.
There are lots of reasons for it and I think the biggest one is internal spend is far more than the external spend. Gartner estimates that CSPs spend more than 50% of their total BSS/OSS spend intenally rather than externally. So if BSS/OSS providers could convince these CSPs to outsource their operations to them, it could be a big plus. But the problem here is CSPs are comfortable outsourcing their operations to individual software vendors and they look to outsource their operations to one big SIs or outsourcing company such as IBM or Accenture. BSS/OSS have so many parts that CSPs end up buying different solutions from different companies so its virtually not possible for them to outsource these small parts to individual companies. So even if outsourcing grows, BSS/OSS providers stand to loose out if they dont have very strong relationships with firms like IBM, Accenture, Tatas etc.
The second one is traditional carriers have historically considered BSS as a big differentiating factor, and most CSPs today incorporate the idea of network enablement and wholesale service to other providers as part of their strategic plan. This is good in a sense that their are wholesale BSS/OSS opportunities for vendors but bad in a sense that any new operators would use the services from existing provider rather than buying it from BSS/OSS vendor. In developing markets where a strong wireline/wireless incumbents exist, some new entrants and mobile carriers will use the existing BSS of the incumbent operator: the same is true in almost all MVNO operations except the largest. New BSS will seldom be purchased complete in mature markets, as relatively few Greenfield operators enter: in fact, consolidation is the watchword in most of the developed markets today. The biggest bright spot I can see today is in convergent players who may seek to purchase new support systems for their new convergent services and offers. But even here it's likely they will rely at first on existing solutions from legacy carriers, especially as they test the waters with new customers the latter have served for decades.
New services, upgrades to broadband-level infrastructures, content and convergent developments in devices and applications will bring additional opportunities to upgrade and add on to existing BSS/OSS. This will be particularly important in countries that are moving toward Open Access Networks (OAN), including Singapore, Australia, New Zealand and Malaysia. Some governments are offering incentives in the form of grants to boost network investment, and BSS/OSSwould be one such priority.
In South Africa, the government has made a distinction between network operation licenses and those for service provision, which will emphasize the need of the network operators to provide BSS/OSS services on behalf of potentially hundreds of new entrant providers. Then there are operators who are winning additional services licenses for example a fixed line operator winning a mobile license and vice versa. Iliad in France, Telkom in South Africa could be examples of this, and would likely require new BSS/OSS functionality as and when they start their services after getting the license. The same will be true in most cases where new mobile licenses are being offered in the emerging world, although much uncertainty exists and if a regional power (such as Zain or MTN) wins a license in a small country it's not as likely that it would need to purchase new BSS/OSS capabilities.
Similarly, power and cable utility companies in Latin America have received regulatory encouragement to enter communications services. While power and utility companies already have BSS systems, they would have to upgrade their systems considerably if they want to become a serious competitor in the market (including broadcast TV, broadband, mobile).
Obviously based on my research there are companies which I think would buy new or upgrade their BSS/OSS systems, I dont think I have the liberty to publish it here.
Overall I think BSS/OSS space is still very exciting and a growth industry. Vendors need to invest in new verticals and markets where new regulations or services could create new requirements for BSS/OSS products. Vendors should also go out and forge some strong relationships with big outsourcing companies so that they can partner with them in BSS/OSS space. Acting like a traditional BSS/OSS vendor is not going to be good recipe for growth.
