The values of the project should be kept in mind for all team members because the goal may change.

The lack of explicit discussion about why and how the mission had to change created a wedge between participants. Reminding team members about the values underlying the project — promoting sustainability, urban livability, innovation — could have helped bring all of them back into the fold. Instead, the team found itself split between those enthusiastic about the new goal and those who clung to the old one.

In 1850, Charles Dickens published "A Christmas Tree". The short story opens with a description of the tree " lighted by a multitude of tapers" and decorated with ornamental guns, pincushions, pen wipers, sugarplums, " teetotums" and " hummingtops ". Despite the fertility of his vision, however, Dickens made no mention of spray-painting the tree a brilliant shade of purple.
