Безвозмездно, то есть даром выкладываю статьи по Software Product Management: Номер 1 Sponsor, customer, integrator and developer should get completely different material in the presentation. Sponsor always wants to know how much time does it takes to enter the market, where we can beat our competitors and what profit he can earn to understand the investment strategy. Customer is interested in features and benefits of product implementation and how much OPEX he can save, and what payback time for the business case is. Integrator is looking for the margin and new markets, so he would be interested in customization opportunities for the product in order to easily deploy it widely and add its value as a value added reseller. Finally, developer wants to see a strong interoperability and API, well commented code and good documentation. Please take a look at the table with the contents of a typical product presentation. Добавлено через 40 секунд What is the difference of the OSS role in the Service Provisioning Process between the wireless and fixed carriers? To understand fundamental difference in the role of OSS, let's take a look at difference in the nature of Service Provisioning Process in fixed and wireless carriers. Wireless Operators (2G/3G/LTE) are using radio coverage as subscriber access. Fixed carriers (ADSL, FTTH, GPON, etc.) are using various technologies of ground access (copper pair, fiber, etc.). By including new radio base station, wireless carrier immediately creates the potential access channels to the subscribers within the entire coverage area. By including new hub, fixed carrier will get only the technical ability to connect the subscribers within one building or even one floor. To connect to the mobile operator subscriber need only register their mobile terminal in its network. To connect to a fixed carrier the subscriber must leave a request for connection and wait for the construction of transmission lines to his home or office. It is obvious that the Service Provisioning Process of fixed operator is much more complicated both from the technical side and organizational. Fixed operator has to take care of the constant and rapid construction of the core network, access network, distribute and optimize labor resources inside the installation teams, monitor the connection of subscribers in a timely manner and so on. You should also take into account that the fixed carrier expansion to the next house or office creates inevitable costs for the construction of linear facilities, and each of the operators need to determine those homes and offices that will provide more profit among the others and connect them first. This is not the entire list of difficulties faced by the fixed telecommunications provider in Service Provisioning Process. At each stage of service delivery the role of OSS at the fixed operator is significantly higher than at mobile carrier. If mobile operators can take advantage and convenience of using radio access and use OSS to provide the additional services in a cost effective manner, the fixed operators are unable to provide even the essential services without OSS. However, wireless carriers now promoting commonly service bundles. Wireless service bundles have become so complex that synchronizing billing and provisioning requires great technical dexterity and of course the role of OSS has become more important.
