The cafe app that nobody asked for

Sam's cafe plans a new booking app. Sam is happy about it. The cook is not. "Who will teach us? What will it cost? Will it break on Saturday?"

Sam did not ask these questions first. Now the staff do not trust the app.

Before a change, an organisation must study its effects, plan what it needs and talk to the people it touches.

Impact: measure, then forecast

First measure how things are today. This is your starting point. Then forecast how things will look after the change.

Look for good effects and bad effects. If a change only looks good, it has not been studied well.

Worked example: measure, forecast, compare

Try it: work out each change

Code: python
now = {"calls": 40, "mistakes": 12, "cost": 50}
later = {"calls": 10, "mistakes": 3, "cost": 120}

for name in now:
    change = later[name] - now[name]
    if change < 0:
        print(name, "falls by", -change)
    else:
        print(name, "rises by", change)

# Add "training": 0 to now and 20 to later, then run it again.

Analysis: weigh the two sides

Now compare. Make two lists: the good effects and the bad effects. Ask how big each one is and how likely it is.

In Sam's case, fewer mistakes and calls save time every week. The training happens once. The cost stays small. So the answer is: go ahead, but plan the training well.

Resources: what the change needs

A plan needs resources. There are five to list.

Budget: the money. Time: the days and weeks. Staffing: who does the work, and who covers their usual job. Hardware: devices such as tablets. Software: programs, and the permission to use them.

If one is missing, the change stops.
