I was reading a research paper on TRIZ in service sector(http://www.realinnovation.com/archives/2003/12/d/04.pdf) where it explained that Service development is differentiated from physical product development because of the unique characteristics of service products, such as customer participation, simultaneity, heterogeneity, intangibility and perishability, etc
- tighter coupling between marketing and operations aspects. Service Operations integrates customer experience management involving customer service, operations, marketing etc
- Since end product is intangible, the soft skills matter a lot in front end roles, so this percolates into the (otherwise) non client facing roles too like finance.
- Inventory does not exist in service sector-so this is both a boon(less logistics hassle) and also a nightmare(manpower utilization)
