IHE Pipeline Impedance Matching
It is important for the Planning Committee to evaluate the flow of profiles through the IHE pipeline in their Domain from relevant idea through to deployed systems having a positive impact on healthcare.
At each stage, a key resource needs to be sufficient to properly accomplish the activity at that stage.
If there is a mismatch in the capacity of adjacent stages in the pipeline, the Planning Committee is responsible for taking action to smooth out the flow, either by "widening" the narrower pipe by increasing the resource, or by throttling back at the prior stage. Otherwise the overloaded activity will be done poorly or work from the prior stage will be set aside/wasted.
Consider the following stages in your domain. In which stages is the activity lagging for lack of input, in which is the activity suffering from overload, in which is the flow well matched to the resources? What is your action plan to fix the balance?
