Be careful not to overbrief. Any briefing that takes more than a few minutes is likely to make the other guy switch off and will achieve absolutely nothing.
Any variations from company standard operating procedures absolutely must be briefed as should any expected variation from the procedure on the chart.
However, the statement "Standard calls and procedures" should suffice unless you have serious doubts about the competence or inexperience of your colleague.
To turn up for work not knowing your company SOPs amounts to criminal negligence.
You could ask your colleaugue at the end of the briefing if he is happy with (for example) the standard Cat 2 procedure or the Go Around procedure. If the answer is "No" then rebrief him/her and then contact the Chief Pilot at an early opportunity and suggest some further training. Otherwise the same thing is likely to happen next time.
