value chain &process-stategy matrix

In the 08/06 paper Q2, the question is as follow:
The Business Architecture Committee (BAC) has been asked to make recommendations on the sourcing of
activities (in-house or outsourced). The BAC has also been asked to identify technological implications or
opportunities for the activities that they recommend should remain in-house.
Suggest and justify recommendations to the BAC for each of the following major process areas:
(i) Attendance of repair staff at breakdowns;
(ii) Membership renewal;
(iii) Vehicle insurance services;
(iv) Membership queries; and
(v) Vehicle history checks.

the answer use the process-strategy matrix to analyse the complexity and the importance in order to decide whether remain inhouse or outsource.
i was wondering whether i can use value chain model to analyse. Because value chain is a model that can help us know which activites add value and which activities is of little value so that we can outsourse?
