This is an interesting article comparing the different approach available to you depending on whether you want to fill your Senior vacancy from an active candidate pool or a passive candidate pool.
Active candidates can be attracted through online advertising, from a robust candidate pool or by using Contingency Recruitment Agencies. They can provide short term solutions to “put a bum on a seat” and alleviate the short term pain you suffer when someone resigns. Passive candidates on the other hand need to be identified, engaged and courted before we are able to introduce the idea of new job opportunities to them. This requires a proactive strategy that can be delivered by an effective Executive Search partner. Retained Executive Search needs to be the start of your solution and not considered as a magic wand when all else fails. It is a strategic approach that requires a considerable investment of your time and money and so needs serious consideration.
