The template looks pretty good but just a few points about your template. Nigel Hamilton retired mid last year from the NICS and was replaced by Bruce Robinson http://www.ofmdfmni.gov.uk/index/about-ofmdfm/about-the-department/bruce-robinson.htm
Also looking at the organisation structure and website in general I don't think the Northern Ireland Bureau and the Office of the Northern Ireland Executive in Brussels are executive agencies but branches of the department. http://www.ofmdfmni.gov.uk/principal-establishment-and-finance-officer
Looking at that take a closer look it doesnt look like anything other than a publication rather than an organisation, have seen copies about the place. The website doesnt seem to work for me at the moment.
Finally Ian McCrea replaced Jim Wells in Sept 2008 http://www.niassembly.gov.uk/centre/2007mandate/centrehome_07.htm
Otherwise looks alright, might be an idea to do one for all departments.
