Should I include paper organization in the Introduction?

Well, if your paper organization reads like an abstract story, you should include it; otherwise not. If you are willing to spend that extra bit of time to make your paper organization meaningful, then only include it in the paper. Otherwise it is just waste of very precious real estate.

Do Not Include

Related works are discussed in section II. In section III we propose a model for privacy measurement. A prototype implementation is described in section IV. Experiments and results are detailed in section V. We summarize the paper in section VI.

Include

The paper begins by enumerating existing privacy models in Section II. It is found that the previous models do not consider implicit channels of privacy loss. Consequently, a privacy model is proposed in Section III that considers both implicit and explicit channels. In order to validate the proposed privacy model, we implemented a prototype system that is described in Section IV. We compared the proposed model with three state-of-the-art models in Section V. The experiments lead us to interesting findings which are listed in Section VI.
