Difference between zone 2 and zone 3b components in the agile literature review approach

Difference between zone 2 and zone 3b components in the agile literature review approach (ALRA):

Zone 2 ["existing" organizational capabilities] components are about evaluating existing capabilities of an organization while zone 3b are about evaluating ongoing and proposed change initiatives in an organization. Thus, one can come up with a zone 2 component on "to evaluate the target cost management (TCM) capability" of a company if TCM is an existing activity in the company and the evaluation is on the existing TCM capability of the company. 

If the researcher's intention is to evaluate what needs to be done to build up new TCM capability in the company, it is a zone 3b (solutions-related) component, not a zone 2 component.
