As client-server technology passes on into the history books this is probably the strategy that everyone will follow, but in these early days of e-HR the situation is not so clear. This will probably be the most expensive solution and may be politically difficult to justify and technologically difficult to implement. Because e-HR systems use industry-standard technologies such as browsers and intranet servers, many organisations will find that they have already made much of the necessary basic investment. However, many suppliers will charge per user, even though it may not be necessary to install separate client software. Surveys have shown that, on average, the implementation time for an e-HR system is reduced by 20 per cent when managed by an ASP. A team to make a decision about an e-HR implementation should: have a diverse membership that represents all interested parties at different levels, include someone from board level as a sponsor, and be prepared for some complex decision-making.
