3.33 The Department believe it is likely that the scope of the contract will change in any future competition. Telecommunications services currently covered by separate contracts, such as mobile, satellite and certain e-mail services, may be incorporated. Market developments such as the current trend towards the increasing use of mobile telecommunications may also need to be reflected in the new contract. Other suppliers perceive BT as having advantages in the delivery of fixed telecommunications. The Department believe, however, that the inclusion of other types of service where BT is less dominant is likely to encourage other suppliers to bid. We believe it is likely there will be many changes in the telecommunications industry over the ten years, and a change in scope of the contract may improve the number of other suppliers prepared to bid. Nevertheless, BT will still have the advantage of their experience and knowledge of the Department's requirements, and the Department will have knowledge of BT's ability to satisfy them.
