There have been some interesting posts recently on twitter that seek to harness all that we know about what makes an effective professional in applied industries. Two from @ JamieColes1993 https://twitter.com/JamieColes1993/status/935195210421809152 https://twitter.com/JamieColes1993/status/933692766542073856 Another from @laurent_bannock https://twitter.com/laurent_bannock/status/933001135069319168 I think these attempts are outstanding in developing the argument for the need for blended skill set, not just technical, but craft skill too. I am often asked if folks should pursue accreditation. The reality is that many are working without it. Many believe in acquiring badges above that of experience - which will ultimately lead to a worsening of the industry reputation. Overall I think experience beats qualifications, but qualifications add the legitimacy and credibility that the profession requires. A future high performance system will require both, because as the stakes go up, the risks do to. Would be interested to hear thoughts on this.
