Morning Edd - far from clear whether this is a purely hypothetical question or one that e.g. you might have been asked to do a presentation for as part of being interviewed for a new job.

But either way, the answer is going to depend on how much you know about the "new company" and equally how much you should know about it.

Your Forum profile and past contributions suggest that you are likely to work for an organisation with a finger in the rail pie.

So, as example, if you work for Network Rail but are being asked to say what you would do in the first 30, 60, 90 days working for a Tier 1 or even Tier 2 Contractor you should be able to do the preparation to give you a good understanding of where that Contractor is in terms of its health and safety management systems and for a senior role you should be aware of the somewhat sensitive issue of their recent prosecution (or whatever) following such and such incident.

Exactly the same applies if you are working for such a Contractor and being asked what you would do if newly working for another such Contractor or Network Rail. 

In contrast, if you were making the same presentation to say a food manufacturer (that your company has no signficant commercial relationship with), it might be unreasonable for the audience to think that you should have a good prior understanding of what makes that organisation tick. They would expect you to have done some homework, e.g. to find out whether or not they have their ISO accreditations but it would be unreasonable for them to expect you to guess how their systems have been developed. You are also less likely to be aware of that "sensitive issue".

two things I look at when going into any organisation - risk management and distaster and emergency management (DEMS)...

1. If thier risk management is under control  - risk assessments and actions high risk activities etc.then happy to look at improving the DEMS.  All high risk ascitities should have no outstanding actions (30 days) if not in place resolve within 30 days then medium within 60 and low within 90.

2. If point 1 isn't under control and the DEMS is s**t then panic! Regulated facilities then 3 yearly training plan and update to procedures within 30 days, - annual scenario walkthrough desktop and 3 yearly practical.

Once you start with these two topics you won't starve for topics to add...
