At this stage you will find that you may need to account for both quantitative and qualitative benefits measures, using either direct measurement units or proxies if this is more complicated. You may find it beneficial to use Social Return on Investment (SROI) methods and techniques to identify more qualitative benefits and then to be creative concerning how to represent them in numerical terms.
Case studies, vignettes and other social science evidence-based methods may be used in conjunction with the more classical financial and non-financial performance KPIs and Metrics. SROI is now accepted as an investment appraisal method to justify business cases for transformation change and improvement programmes especially Digital IT projects in the UK Public Sector and the NHS.
Determine if your application will produce a range of benefits that will be difficult to quantify in a classical accounting fashion. This can be typical for healthcare applications where they might produce a noticeable change and influence on wellbeing, mental health, quality of life or knowledge about illness, diagnosis, treatment etc.
SROI can help with the development of a robust business case and RDV/BRM plan that will highlight such impacts in order to justify financial and resource investment – which in many cases may need to be longer term and more sustainable for future Digital Transformation Projects.
