Best Software Tools?

I am running a research project and trying to identify software that improves productivity or “changes the game” in the following property industry areas:

• Commissioning Management
• Commissioning
• TAB
• Project Managment
• Project documentation management 
• CRM for professional services firms 

I am not interested in Primavera, AutoCAD, REVIT or Salesforce.com. These are all well known and frankly too specialised and expensive. 

What I am interested in is are software applications, new and existing, that are being used effectively to automate or improve processes and work flow. 

For example, on a mega airport project WhatsApp groups are being used by the commissioning manager to improve communication and work flow efficiency. Frankly, on this project, it is a game changer. 

Message me (Twitter ) or reply with your thoughts and experiences.  

Thank you…..
