Preferred option
You now need to review the six options that resulted from your review in Candidate options and decide on the preferred option.
How detailed this process needs to be will depend on two factors. The first one will be the degree of consensus within the team. If you all agree after due consideration that while it would be nice to do two pilots you do not have the resources then that option can be dropped. Similarly if you cannot afford all the extra vendor services then that might need to be dropped. If by this process of elimination you can agree the preferred option then you are ready to go to stage five and do one detailed business case. If you cannot agree then you may need to do a business case for both options and make your decision based on that. This will increase the workload at stage five, however.
The second factor will depend on what your stakeholders and project board require. If they decide that they need a business case for each of the options that you have considered in Candidate options then you will need to do a high level business case for each option. If they are happy to accept the recommendation of the team on the preferred option in section on preferred option then you can just do one detailed business case for the preferred option.
