12.2.5.3  Resource utilization
The software design solution must provide for the efficient rationing and utilization 
of scarce computing resources. During software design synthesis it is important to 
establish resource utilization budgets against which structural specifications can be 
established. This budget should provide an understanding of anticipated resource 
consumption profiles for each thread of behavior. Further resource budgets can be 
established for individual structural components and units, if desirable. Engineering 
assemblies may be needed to establish resource monitoring stubs to capture actual 
resource consumption profiles and provide a basis for resource utilization optimi-
zation. 
Figure 12.4
 identifies the software architectural design and implementation 
flow to ensure that resource utilization budgets are successfully realized.
Software engineering involves a number of design strategies associated with 
resource utilization that must be considered to establish an efficient and effective 
design solution. During functional analysis and allocation, the software behaviors 
should involve the resource allocations among functional threads and individual 
components and units. Resource supervision behaviors should be incorporated into 
the behavioral models to evaluate multitasking scheduling, task prioritization, and 
resource queuing strategies. During design synthesis these results should be incor-
porated into the specifications of structural components and units. Resource critical 
structural components should be identified as engineering assemblies that specify 
the resource utilization stubs needed for a performance evaluation.
