Introduction of new technology into an established field of work takes an initial period of adjustment. Not only is the technology new, but it has unforeseen impacts on work practices and policies. In each of the three CPS mobile technology initiatives much was learned to inform subsequent phases. For the future, we recommend that more can be learned from those caseworkers who have used the device for over six months. After they have worked through their initial period of adjustment, their mobility and use, productivity, and satisfaction can be better assessed. In addition, it is important to assess how they have incorporated the technology into their work after they come through the normal learning curve. Focusing on this stage will yield different and possibly more meaningful results about long-term change.
