BmTS Deliverables
A number of standard, generic end-to-end processes for collection, analysis and dissemination of statistical data and information.
A disciplined approach to data management, using a standard information lifecycle for all statistical data and information across the organisation.
An agreed enterprise-wide technical architecture which would build up "over time a portfolio of standard solutions and components".

Change of Plan
Over the next two years (2008 - 2010) focus on the preparation of a robust Investment Case, for separate funding of the BmTS development;
Focus will continue on standardising processes or methods, using technology as an enabler only when the value is proven;
While there will be no further direct software development of BmTS Components, projects will still be encouraged to adopt proven deliveries, and a team will work to ensure that the wider organisation is made aware of these deliverables

Options in 2008
Take no specific action and rely on obtaining funding;
'Migrate All';
'Redevelop All';
Undertake a phased, multifaceted approach to resolution.

Lessons learned
Don’t assume a single source of complete information;
Expect to uncover issues as we look into these older systems;
Be prepared to continually re-plan as new items come to light;
Work closely with partners (business owners, data archiving, architects)
Communications - keep the message alive (success stories);
Test, test, test (especially the translated code)
