1.3 Lots: is this call for tenders divided into lots?  This call for tenders is divided into two lots:  Lot 1: Primary channel for TRANSFORM initiatives, primarily covering IT services on  project-based activities for the construction of new products and other specialised  services.  Lot 2: Primary channel for RUN and GROW initiatives, primarily covering IT services on  project-based activities covering the enhancement of existing products and delivery of  established services such as keeping the products up and running, address changes,  fixes and user support activities.  Tenders may be submitted for both lots. Each lot will be assessed independently of the  other lot. Tenders which cover only part of one lot or are declared as being conditional  on the award of the other lot are not permitted.
