What is the blast radius of your next role change?

A role change rarely affects just one role.

It can affect:

→ Hundreds of users
→ Multiple business units
→ Sensitive access
→ SoD exposure
→ Existing mitigation controls
→ FUE classification

That’s why I like the term 𝗯𝗹𝗮𝘀𝘁 𝗿𝗮𝗱𝗶𝘂𝘀.

Before changing role content, the important question isn’t simply:

“𝗗𝗼𝗲𝘀 𝘁𝗵𝗶𝘀 𝗳𝗶𝘅 𝘁𝗵𝗲 𝗶𝗺𝗺𝗲𝗱𝗶𝗮𝘁𝗲 𝗶𝘀𝘀𝘂𝗲?”

It is:

“𝗪𝗵𝗮𝘁 𝗲𝗹𝘀𝗲 𝗱𝗼𝗲𝘀 𝘁𝗵𝗶𝘀 𝗰𝗵𝗮𝗻𝗴𝗲?”

A technically correct modification can create unintended consequences somewhere else.

And the larger the environment, the harder those consequences are to see manually.

For project teams, this becomes especially important during:

• S/4HANA programs
• Role redesigns
• Organizational changes
• Acquisitions and divestitures
• Large remediation exercises

You want to know the impact before the transport.

Not after.

If you’re planning a significant SAP role change and want to see how we evaluate its blast radius, feel free to message me.
