pretend your organisation, your people, your talent to be your crowd. Haven’t they always said that everyone is your customer, so do crowdsourcing for internal ‘issues’ too. See here a simple advice. Really make it also simple and have 3 groups of a diverse range of people – by inviting them to sign – up in an genuine invite in your newsletter/email (you do have them don’t you, these regular communications, no? well start now!). Just see what pops-up. Don’t let HR or Marketing be in charge, let them be in charge.
