+mindmap
+root{{Server Procurement Takes Too Long}}
+  (Material)
+    not sure what hardware requirements to use as a baseline
+    obsolete hardware specifications
+    high demand for specific hardware components
+  (Vendors)
+    convoluted, slow billing process
+    limited vendor options
+    long lead times for hardware delivery
+    inconsistent communication from vendors
+  (People)
+    too many approvals required
+    unclear when costs for server are passed to client
+    client is unwilling to procure server
+      budget unavailable until milestone is met
+      does not see the need for the server
+      already has on premises servers
+      client does not want to use public cloud infrastructure
+    lack of dedicated procurement personnel
+    miscommunication between teams
+  (Systems)
+    procurement is not automated
+    outdated procurement software
+    lack of integration between procurement and project management tools
+    manual tracking of procurement status
