Technology Readiness Levels (TRL) has become a standard approach to assessment of technological development projects. The origin of TRL is the US moon rocket programs. However, to develop and put intopractice advanced technology projects, also other aspects are important to evaluate in a systematic way.

This paper provides a tentative analytical model of four main perspectives to analyze readiness levels of technology projects; Technology Readiness Level (TRL), Political Readiness Level (PRL), Social and Societal Readiness Level (SRL), and Commercial Readiness Level (CRL). To be successful we need to explore and understand the process, interconnectivities between and the impact based on all those four aspects in an integrated way.
