Common services are similar to collaboration between different organizations, such as a hospital trust or a police force. Neighbouring trusts can, for example. B, decide to work together by merging their HR or IT functions. Traditionally, the development of a shared service organization (SSO) or shared service centre (SSC) within an organization is an attempt to reduce costs (often tempted by economies of scale), standardized processes (by centralization). A baseline evaluation study by the Global Service Centre[6], conducted by the Shared Services and Outsourcing Network (SSON) and hackett Group, which surveyed more than 250 companies, showed that only about one-third of participants were able to achieve cost savings of 20% or more from their SSo. At NASA, the move to a shared services model in 2006 represents nearly $20 million in savings per year. In addition, NASA`s Shared Services Center is expected to save more than $200 million by the end of 2015, according to NASA`s Director of Service. [7] There are reports of common service centres in the UK government that have not achieved savings, such as the Department of Transport project, which Parliament`s Public Finance Committee has described as a “skrunend incompetent”. [11] There are two arguments in favour of service sharing:[1] The “less than a common resource” argument and the argument “efficiency through industrialization”. The first is “obvious”: if you have fewer managers, computer systems, buildings, etc. If you use fewer resources, costs will be reduced.

The second argument is “efficiency through industrialization.” This argument assumes that efficiency gains are due to specialization and standardization, which leads to the creation of front and back offices. The typical method is to simplify, standardize and then centralize using a computer solution as a means. In the conflicting society in which we all live today, it is very important to reach a strong agreement. A shared services agreement is the easiest to legally approve if it is formulated as short and soft. A simple, short agreement facilitates access to other public bodies on the same side. For the establishment and operation of a common service, calibration and measurement are considered by some to be a necessity. Performance calibration is usually the comparison between performance and the best in the class. The measurement is carried out using agreed key performance indicators (KPIs). Although the number of KPIs selected is highly variable, it is generally accepted that fewer than 10 carefully selected KPIs give the best results.

[Citation required] Many large companies, both public and private, are now considering using ECM (Enterprise Content Management) technology as a shared service. It is important that the common service unit be able to compete with other external suppliers. Business sectors must be subject to market discipline. You should also be able to search for support services that meet the same standard.
