About the work

Why the work is being done
Our Defence customers require new capabilities to meet their aspirations of improved interoperability and user experience in the Geospatial domain. These can’t be fully met by existing TDAs.

There is a need to develop the current TDA3 application so that it can be deployed on Met Office and Defence customer environments, allowing pre-existing systems to be retired and new capabilities to be delivered.

Pre-existing TDAs use deprecated technologies which are not sustainable for our customers.
Problem to be solved
There is a need for continuing development of point based TDA3 based on an existing Java Springboot based architecture.

Development of area based TDAs based on a new architectural approach is also required.
Who the users are and what they need to do
Users are typically Defence meteorologists who use the outputs generated by the TDA3 system to determine the potential impact weather may have on Defence related activities around the world.

The TDA3 system is also available for use by external organisations and countries, subject to MOD agreement.

TDA3 can also be configured by users to produce data files for driving third party applications that are used by MOD.
Early market engagement
Any work that’s already been done
Over the last two years TDA3 has been developed to the stage where it is now being used operationally by selected users. Over 50% of the functionality needed to retire pre-existing systems has been delivered.
Existing team
The Met Office in-house team consists of 1x Product Manager, 1x Solution Architect, 1x Technical Lead, 2x Back-end Developers, 1x Test Lead, 1x Project Manager. An additional Met Office developer will join the team early in this development.

We have also been working with an incumbent supplier for development of the user interface and would anticipate a handover period to the successful candidate.
Current phase

Work setup

Address where the work will take place
The successful candidate will be expected to work at Exeter Met Office HQ during handover and on-boarding activities.

Remote working will then be preferred with regular attendance at Exeter Met Office HQ as agreed with the Met Office (see Working Arrangements).
Working arrangements
A limited number of hot desks are available at Exeter Met Office HQ.

Minimum engagement will be attendance at daily "stand-ups" (including remote attendance).

Any supplier Technical Lead will work under the supervision of a Met Office Technical Lead and Solutions Architect.

Outstanding work is logged in a product backlog which is continuously updated and prioritised by the Met Office Product Manager.
Security clearance
SC cleared supplier staff will be required as soon as practicable.

Questions asked by suppliers

1. Has the incumbent supplier been involved in the Beta product development to date, as opposed to just developing the User Interface?
Yes, the incumbent has been involved in Beta development of the entire software stack in collaboration with the in-house team. But most of the incumbent supplier’s effort has been directed towards delivery of a new UI.
2. Regarding "Demonstrate provision of a securely managed working environment outwith the Met Office environment". Did you mean "outwith" or is this a typo?
Yes we did mean to say outwith. We are looking for a demonstration of how the supplier would look after Met Office assets outside the Met Office control. For example, how would the supplier manage Met Office assets remotely?
