The guardrails are our agreements with each other across the enterprise. However, each role usually manifests these in a different manner. The following is what the guardrails mean for a business architect.
Work on items that will realize the greatest amount of Business value across the enterprise
The business architect’s role is to ensure that any impact working on those MBIs at the top of the list do not adversely affect other capabilities. Doing so would lower the amount of business value actually realized since there would also be a negative impact.
Collaborate with each other in order to maximize the realization of Business value across the enterprise
New capabilities often affect others. It is important that different parts of the organization work together to ensure adverse effects are avoided. The business architect must ensure what is required in this collaboration is made visible.
Ensure that all work will be made visible
Dependencies between capabilities is often obscured or even unknown – especially when subject matter expertise has been lost. One of the business architect’s role is to make these visible.
Take the necessary steps to sustain or increase predictability
In many ways this could be considered the defining goal of the business architect. When building one capability adversely affects another capability, unpredictability results.
Keep the work throughout the value stream within capacity
Unseen dependencies between different parts of a system typically results in integration errors and a change in one part of the system breaking another part. This new, unplanned work (waste), adds work in process. Since it was unplanned for, it will likely overload the development groups affected and even their product owners/managers as they will likely need to get involved to sort things out. In addition, this often has a ripple effect to other groups that are dependent upon those teams directly affected who are not involved with this functionality but are dependent due to other capabilities.
Encourage everyone to strive for continuous improvement
Helping different groups collaborate is a never ending job.
