OSS/BSS Testing And AMSBy Ahmed Adel Abdel Gawad
OSS (Operations Support Systems)/ BSS (Business Support Systems)• OSS (Operations Support Systems) track network inventory, assets and provisioning of services, while BSS (Business Support Systems) deal with customer relationship management (CRM) and processes such as taking orders, processing bills, and collecting payments.
OSS/BSS landscape• The OSS/BSS landscape can be broadly divided into the following modules: •Mediation Systems •Billing Systems •CRM - Customer Relationship Management •E-Business & Web Self-Care •Data Warehouse - Business Intelligence & Analytics •Provisioning Systems •Service Assurance & Network Care •Fraud Management
OSS/BSS landscape• Business (Testing) Prospective – Customer Life Cycle • Customer Life Cycle and dismissal • E-Business & Web Self-Care • Customer Relationship Management • Loyalty Systems • Billing Systems – Service Life Cycle • Service Life Cycle • Service Management
OSS/BSS landscape• Technical (AMS) Prospective – FrontEnd Systems • Web Services • Application Servers • CRM • ERP – BackEnd Systems • Database • Service Assurance & Network Care • Provisioning Systems • Billing Systems • Warehouse • Business Intelligence & Analytics • Payment GW – Mediation Systems • Provisioning Systems (ASAP) • Fusion MW …
Target Approach• Introducing (TaaS) for OSS/BSS Business and Systems.• Leverage testing team to serve business instead of customer.• Building testing repository for all business related to Telco. Industry.• Automat Testing Process for regression and production support.• Provide AMS for OSS/BSS Environments

Testing Services MarketWhy Testing-as-a-Service? Client Challenges Business Value Scope of applications are organically defined as Reduce system outage risk caused by functional and market conditions change performance defects • Standard contracting models do not provide cost No upfront investment or recurring/maintenance fees effectiveness in such scenarios Forecast the consumption of testing services and There are much more frequent peaks and valleys control testing expenses accordingly in testing demand Clients are looking for their Testing providers to: • Testing resources are still available and being paid for in valleys of idle time • Build the tests, automate and execute them (or have them ready to be executed by the client) Capital expense on software tools and tool infrastructure and ongoing costs for support and • Use industry leading software tools like maintenance ALM/Quality Center and Performance Center Smaller projects often don’t have budget for • Use a professional certified testing team and test engaging full time testing resources center of excellence • Use a formal Quality Management methodology with pre-built tests/scenarios, frameworks and accelerators3/17/2013 9
