- IFS233 Donell Consulting recently completed an IT training platform implementation with a public firm. The project concluded after the completion of a testing, piloting and sign-off from the project stakeholders. Though completed, the project manager was reviewing their notes, in which they listed all the important occurrences that were recorded during various project phases: ● The pilot of the training platform is about to begin, and the COO of the firm has informed the project team that they want an additional 1000 staff trained and included, and the firm will be increasing budget accordingly.
