Order Description

You are speaking with a client about different Open Innovation tools (Open Source, Lead Users, Crowdsourcing, Intermediaries) which can be put in place in his firm. However, the client while you are saying to him that Open Sourcing, Crowdsourcing and Intermediaries are three distinct instruments of Open Innovation, he stopped you saying that Open sourcing and Intermediaries actually appear to be different forms of Crowdsourcing.
Critically discuss this statement drawing appropriate examples.
