Datacenter power maintancence - Sequence of devices shutdown

We are in the process of upgrading the power in one of datacenter and we are planning to take all the devices down before we touch the power.
We have categorized devices in to multiple layers as below.
Servers                        
Layer -1       Application level preparation (Stop feeds, Log shipping, role switch etc) & Applications/ DB and application level                   
Layer -2       Individual servers (application already shutdown \ servers with only OS shutdown and no apps shutdown required)                  
Layer -3      Clustered servers connected to SAN & Clusters                  
Layer -4      Storage & Backup                  
Layer -5      Name resolution servers Consoles & storage switches                  
Networks                        
Layer-6       Access switches & voice equipments                  
Layer-7      Server farm & Distribution switches                  
Layer-8      Core network layer components & Tier-0 Routers                  
Layer-9      Vendor devices Like MUX etc.      
            
I would like to get a template using which I can take care of flow (derived based on dependencies)  of the shutdown and ensure that everyone is following the flow properly. I can think of putting it in excel. But I am looking for workflow kind of page (Hosted in my intranet, where everyone will get authenticated with their login name) also everyone can see the flow and confirm (by click) once they are done with the shutdown of their servers.
By doing this I am ensuring that everybody follow the flow and they provide their confirmation in writing (in the webpage where the comment will be entered with their login name) before other proceed with rest of the servers.

Please help.

Thanks
Ram.
