The business stream input requirements vary in nature
and quantity depending on whether the model is being used in “forecasting
mode” or “reconciling mode”.
"Social Housing Property-Based" business streams 
There are ten business streams under this heading from Housing Accommodation
through to Home-Buy. The required input for each one covers Revenue Assumptions
such as unit rents and service charges as well as expenditure items such
as management costs, service costs and maintenance costs etc. Also required
are Development Assumptions covering changes in housing stock, unit build
and demolition costs, sale prices, repairs and maintenance costs etc.
"Social Housing Non-Property Based" business streams
There are two business streams under this heading:
Management Contracts and Other Activities.
The required input for each of these is much simpler, covering growth
in income and level of expenditure. Each of these sheets allows for a
number of business streams within each general category.
"Non-Social Housing" business streams 
There are four business streams under this heading, from Market Renting
through to Other Non-Social Housing. The required input for the three
streams involving housing units require information on revenue and development
assumptions per unit similar to that for "Social Housing Property-Based."
The input for "Other Non-Social Housing" is much like that for
"Social Housing Non-Property Based" and also allows for several
different business streams within it.
Business Plan Accounting Data 
At least one year’s historical data are required in “forecasting
mode”. In addition, 30 years’ projections are required in
“reconciliation mode”. Input consists of the three financial
statements: Income and Expenditure Account, Balance Sheet and Cash Flow
Statement.
