a. Corrective maintenance 

b. Service support 

c. IT Security 

d. Application Management Services 

5. Transition/Integration services, including participation in projects led by the Lot 1 Contractor, takeover and handover. 

## 2.2. Rationale for the use of the lots and their handover 

The division into lots looks at the different skillset required across the dimension of the RGT model and emphasize the specific relevance and focus of the services envisaged under Lot 1 - Transform  and Lot 2 - Grow / Run respectively . 

Considering that ECHA IT Enterprise Architecture is highly integrated and increasingly based on common building blocks, a successful interaction between the two lots becomes necessary and all contractors shall have a core responsibility in ensuring a smooth and fluid collaboration in this direction. 

In this sense, and as one of the building blocks for FWC666, ECHA expects also to leverage on the harmonisation of practices and the use of common toolchains for the SDLC and for Build & Deploy. 

Whereas, a decision of ECHA on the use of the lots shall be deemed final, as a general rule, the work between the lots is allocated according to the following: 

• Lot 1: 

1. Shall serve ECHA in the provision of Transformation activities as described in section 2.1.1. 

2. Shall serve ECHA in the provision of specialised services (e.g. impact analysis expertise etc.) and peer review/ quality assurance activities, in particular for services delivered under Lot 2 but not excluding for services delivered under Lot 1 and subject to the provision of conflict of interest (refer also to section 3.2.4 of the Tender Specifications). 

3. Will be considered when ECHA identifies a transformative initiative. For example, a new capability or a deep refactoring of an existing capability, even though the implementation could be achieved by a combination of Lot 1 and Lot 2 activities (new developments under Lot 1 and changes to existing components identified under Lot 1 but to be addressed under Lot 2). This is typically covered in Inception activities or studies leading to the definition of early architectural blueprints. 

4. Will be considered for the development of prototypes and minimum viable products. Further development may also take place in Lot 1 , subject to ECHA’s decision. If the case, all services necessary to develop, build & deploy, basic maintenance, may be required by the Contractor under Lot 1 until transitioning to Lot 2 (handover/takeover). 

5. Will be considered for the activities supporting the evolution of the ECHA Enterprise Architecture and the definition of new architectural targets within the established governance cycles. 

With regard to the above, it is noted that the initial selection of the contractor in Lot 1 for the delivery of a specific service (e.g. the development of a prototype or minimum viable product etc.) may be maintained for several years (potentially through several subsequent
