If you intend to join the IT industry, then go for Training - it's important to understand the training schedules and the training calendar, etc.
If you are not too keen on IT, then consider focusing on Performance appraisals - when to do it, who should be appraised, how 360 feedback should be used, and when 360 feedback may be ineffective. Also, consider the post-appraisal discussions, etc.
