There are many key factors to enable a BIG scenario. They are not specified by the BIG Framework, but they are stipulated.
Defined lifecycles – different entities will have different phases they go through to be conceived, born, nurtured, developed, adopted, exploited and closed in some shape or form. The BIG model does not stipulate what these are, but it accommodates these needs - for example for different kinds projects, different products, or different service offerings.
Methods – the BIG model does not stipulate how entities are managed, but it does outline the governance agenda that each entity must be accountable into. The Model embraces traditional waterfall, agile, dev ops approaches to delivery management.
Configured Tools – the BIG model does not stipulate tool expectations, but it is assumed that if people are capable to carry out methods and lifecycles, they will select and use appropriate tooling and will be supported as appropriate by the organisation to provide information for governance purposes.
Operating Cycles – to enable the business to operate, certain processes will be based on cadence rather than operated ad hoc, primarily for efficiency and effectiveness. For example, invoicing, payments, resourcing, strategy review, prioritisation etc. These cycles are not specified, but it is assumed that the BIG model will need to align to what an organisation already has.
Capable People – the BIG model does not stipulate people capabilities, but it is assumed that if people are capable to carry out methods and lifecycles, and are supported as appropriate, then they will be able to participate in the governance agenda.
The BIG approach to Key Enablers is to exploit what already exists and improve along the way rather than making the enablers the focus of busienss change.
