To my INCOSE friends - I have switched off all the rubbish I used to get from Yammer. I would be delighted to hear from you if you specifically want to contact me - if you do, you probably have my contact details already (!, though my old Blueyonder email doesn't work any more), or you can message me through LinkedIn. NB - I WILL NOT NORMALLY ACCEPT CONNECTION REQUESTS UNLESS I KNOW YOU PERSONALLY. If I don't know you, and you would like to connect with me, please include in your request a personal message explaining why you think I should be interested in connecting.
