A Value Stream is an end-to-end process that flows horizontally through an organization in order to provide value to a client, patient or customer. Many organizations map processes vertically rather than horizontally focusing on a department over the entity that flows through the entire organization. In a horizontal process design, however, because the entity is what is mapped and not a facility or department, handoffs can be visualized and downstream affects identified.

How Many Value Streams Does Your Organization Have?

Many entities can flow through an organization, but only one entity can flow through a single Value Stream. For instance, a patient would represent the primary entity that flows through a medical practice’s or hospital’s core Value Stream, while a staff member, who also represents an entity flowing through a healthcare organization, flows through an entirely separate Value Stream.

Experience has shown that most organizations have between five and eight Value Streams that either directly or indirectly touch their constituents.

What Makes a Value Stream Map Effective?

For a Value Stream map to be effective, it is critical to determine the beginning and ending points of the end-to-end horizontal process. Identifying the beginning and ending of a Value Stream can easily become an area of great debate.

For example, many may feel that the patient Value Stream begins when a person enters the practice or hospital, whereas others may feel that the Value Stream begins through a healthcare branding campaign. Both are correct, but all must agree on which beginning point to use for the Value Stream. The same goes for the ending point. It is generally best to start the process at the very first point in which the entity is touched and then end at very last point.

Identifying Process Steps

Once the beginning and ending process steps are established, individual process steps must be identified in order of flow. These steps represent a noun and a verb combined to articulate a high level action that is necessary to deliver the entity through the process.

After the high level process steps are determined and aligned into the proper flow, the sub-process steps need to be identified for each high level process step. Again, it is critical that each sub-process step be aligned into its logical flow.  It is recommended that during the mapping exercise, the departmental groups performing each sub-process are named. This allows for a cross-functional visualization for the end-to-end Value Stream.

Defining Core Metrics

After the process is mapped, the core metrics for each Value Stream must be identified and measured. This will facilitate continuous improvement by monitoring and measuring the Value Stream against a patient-stated requirement.

Benefits

Some of the benefits in visualizing the path of an entity as it flows through an organization are:

• Staff members can see how their process directly or indirectly touches a patient.
• The effects upstream processes have on downstream processes become evident.
• When changes are made to an upstream process, it is much easier to model the expected downstream effect.
• When quality and process metrics fail to meet requirements, it is easier to determine the point at which the root cause occurred.
• Hand-offs between processes can be better managed. In many cases, the transition between handoffs is where both defects and delays occur.
• Each process step can be measured in terms of its impact on overall cycle-time.
• It can aid in identifying areas for quick improvement.

Conclusion

Horizontally Value Stream mapping how an entity moves end-to-end though an organization can offer many benefits beyond the traditional vertical way of thinking. This method encourages organizations to take a patient-centered focus in how it manages processes and measures success.
