Figure 5.11: Ratings used in evaluations
The rankings of each option against the criterion are aggregated to identify the option with
the highest relative ranking across all the criteria. This option is identified at this stage as the
recommended option, subject to the outcome of sensitivity analysis.
During pre-consultation we selected the three highest ranked options and consulted on
these, identifying the highest ranked option as the preferred option. For final decision making
we will recommend just the top ranked option unless sensitivity testing shows that the
ranking of the „best‟ two or more options would change in the event of a reasonable change
to an assumption or assessment.
5.5.7 Stage 7 – Sensitivity analysis
As a final stage in the evaluation, we conducted further analysis on a shortlist of the most
viable options considered to check their sensitivity to changes in the assumptions or
assessment.

Stage 7 Purpose Outcome

Sensitivity analysis
• Tests 18 underlying
assumptions for
acute reconfiguration
• Test 3 sensitivities for
out of hospital
To test the effect of variation in the
underlying assumptions in the
modelling.
To assess the likelihood that the
options being considered for
recommendation would withstand
the pressures of expected
fluctuations and change.
To ensure the recommended
option remains the recommended
option despite variations in the
underlying assumptions
5.6 How we used the process during the post consultation phase
On the basis that the process was valid, during the post-consultation period (October 2012
to February 2013) we went through the process for a second time to establish whether the
criteria were right and whether they were applied appropriately. This analysis is detailed in
Chapter 9 parts a, b, c and d.
