Frequently, BPO is also referred to as ITES -- information technology-enabled services. Since most business processes include some form of automation, IT "enables" these services to be performed.
An offshoot of BPO is KPO -- knowledge process outsourcing. Considered by some to be a subset of BPO, KPO includes those activities that require greater skill, knowledge, education and expertise to handle. For example, whereas an insurance company might outsource data entry of its claims forms as part of a BPO initiative, it may also choose to use a KPO service provider to evaluate new insurance applications based on a set of criteria or business rules; this work would require the efforts of a more knowledgeable set of workers than the data entry would. The current definition of KPO encompasses R&D, product development and legal e-discovery, as well as a number of other business functions.
Also coming into use is the term
BTO -- business transformation
outsourcing. This refers to the idea
of having service providers
contribute to the effort of
transforming a business into a
leaner, more dynamic, agile and
flexible operation.
