## 4.7.4. Pricing 

## 4.7.4.1. For scope definition (inception) 

ECHA can request the support of the contractor to define the scope to be delivered in a period. An estimate will be based on the effort required to detail the high-level requirements or the backlog items of a product. As a result of this activity, an estimate for the implementation of the scope defined will be provided. 

A formal quotation will be used as basis for the definition of the relevant SCs or STs in a QTM contract. 

## 4.7.4.2. For defined scope (e.g. projects) 

An estimate for the implementation of the scope defined will be provided. 

A formal quotation will be used as basis for the definition of the relevant SCs or STs in a QTM contract. 

During the implementation, ECHA may request exact quotations to be provided for the items in scope, once the analysis and understanding allows for it (e.g. at sprint level, before coding). The monitoring of the sum of these exact quotations against the overall quotation provided, will help improving the accuracy of future quotations and manage the delivery risks (e.g. if the sum of exact quotations exceeds the capacity allocated in the SC / ST). 

## 4.7.4.3. For undefined scope (e.g. change management) 

When the scope is unclear, (e.g. in change management activities), the features to be implemented will be based on the capacity allocated in the request. As for the defined scope, during its implementation, exact quotations will be provided to be able to manage the capacity and budget allocated. 

## 4.7.4.4. Synergies / efficiency 

When multiple changes are requested under the same version or sprint, the contractor should analyse if the different changes impact the same components, in order to perform them in an efficient manner. These efficiencies can be shown as the cost difference between the sum of individual implementations and the joint implementation proposed. 

## 5. Resources 

The contractor shall have the necessary number of resources matching the required profiles to respond to ECHA’s Service Requests with an offer wit hout undue delay. To maximize efficiency the goal is that the resources remain available as planned throughout the duration of the SC and FWC666 lifetime. Conditions for replacement of resources are
