Leadership galaxy Case 4 of 7

Seven vendors, one lead

The problem

Seven vendors work on the same infrastructure. Without a lead, each one fixes their own piece and nobody sees the whole.

The constraint

Each vendor has its own contract, pace and limits, and the whole must stay consistent.

What I did

01

Seven clear roles

I define what each one does: two cloud hosts, a monitoring tool, an external SRE, an external DevOps, email, a telecom carrier.

02

One point of contact

Everything goes through me: requests, priorities, trade-offs.

03

The full picture

I keep the complete map, so a change on one side does not break something on the other.

Diagram: a lead at the centre of seven vendorsAt the start, seven vendors are scattered and unconnected. At the end, they sit on a ring around the lead, linked to it by seven lines, and linked to each other by a second ring that gives the big picture: two hosts, monitoring, SRE, DevOps, email, carrier.big pictureleadhosthostmonitoringSREDevOpsemailcarrier

The result

Seven vendors run as one team.
