I need to change the name of the service desk but don't know from where to start

[Rosana_Casilli]

My customer asked me to change the name of the service desk from Despliegue de plataformas to despliegue de plataformar + [company names]

the thing is that I can't find where to change that. Is there any where, where I can change that? 

Thanks in advance.
