What’s Schmutzig?

Verschmutzungen per WhatsApp melden – S-Bahn München (

How often do you see a ticketing system bring a SMILE to your face?

You have Jira ServiceDesk or ServiceNow with their automated email ticketing systems which run you through a few email workflows and web frontend updates.

I came across a modern ticketing system which brought a BIG smile to my face.

I was travelling in the S-Bahn München and saw this half eaten banana thrown unceremoniously on the seat by some monkey.

I look around and I see the poster for “What’s Schmutzig?” (What is dirty?) from the S-Bahn Munich.

The poster has very simple steps to complete.

  1. Get the number of the S-Bahn compartment which is easy to find with a sticker with a four digit number and an icon of the wagon
  2. Take a picture of the dirty part of the compartment
  3. Send a WhatsApp message with the picture and the compartment number

I did steps 2 and 3 and sent the message.

I got a generic response within 3 minutes with the confirmation on WhatsApp

I got a custom response within 7 minutes requesting for the missing compartment number.

Once I found and sent the four digit compartment number I got the confirmation that the cleaning team has been informed with a request to rate the general cleanliness of the S-Bahn Munich using the 1 to 6 scale used in German schools.

I gave them a “3”

Within 2 minutes I got a confirmation of the feedback and wishes for a good evening.

The entire conversation took 20 minutes.

I would give them a “1” for bringing a SMILE on my face for their ticketing system.

Do the ticketing systems on our software systems bring a SMILE to our client’s faces?

Scrum Team

Burndown and Valueup

Four teams in one department.

All four Sprints started and ended at the same time.

Four different burndowns.

Team B got up late in the Sprint and filled the Sprint backlog after the Sprint started.

Team A, C and D have the typical slow start for the Sprint getting their teeth into the stories.

Team A waited till the end to do a cliff jump and close most of the stories.

Team B did not manage to finish many of the stories that were planned for the Sprint.

Team C had a constant burndown throughout the Sprint.

Team D was slow till the middle of the Sprint and then picked up speed towards the end of the Sprint.

We tend to analyse Burndowns in teams. Are we analysing the Valueups?
