Q&A Deployment Plan Meeting

[Note from the author: after some fact checking I discovered that I used the Red Card in a wrong way in this blog post. The red card must be used to raise issue like low volume or high temperature in the room, which can lower the quality of the gathering of information. For normal interruptions the yellow card should be used.

This basically means that I had to rewrite the blog post on certain points. This task was more complex than I had expected. The whole flow of arguments had to be restructured while preserving the spirit of this post. So I only added this note.]

Facilitator:  Thank you reading “In Case Of Emergeny Press 1“.  I’ve got green cards from numbers 95, 27, 38, and 23. Number 95, you can ask your question.

Attendee number 95: Did you consider Inspection according to Gilb and Graham?

Speaker: I am familiar with the Inspection according to Gilb and Graham. Frankly I did not consider this method. The question should be rephrased as
“Would you choose Inspection according to Gilb and Graham?”.
Looking backwards it is too far fetched. The people should receive proper training and there was just a block of few hours. Another disturbing element is mentioning the most biggest issues first. This can lead to a lot browsing forward and backward through the deployment plan. This can be quite disturbing.

Facilitator: Number 27, you can ask your question.

Attendee number 27: What was your role in the project?

Speaker: My role was a test coordinator.

Facilitator: I’ve got a yellow card from number 68. Number 68.

Attendee number 68: Why did you call for this meeting? It is not your task.

Speaker: I thought, that it was important. The next step is to make things happen: I planned in the meeting and I became the chairman.

Facilitator: There are no more yellow cards for this question on the stack. So we move on the next green card. Number 38.

Attendee number 38: Did the suppliers provide any deployment plans?

Speaker: All the suppliers provided deployment plans.

Attendee no 38: This looks like a time consuming operation. Was there any reluctance?

Speaker: One supplier did not see the benefits at first. Then he made a Deployment Plan after some talking.

Facilitator: At the moment I’ve got one green card from number 23. Number 23.

Attendee no 23: why did you need a deployment plan?

Speaker: I asked my test team the same question. One of the testers told me, that experience taught, that these plans were necessary. A few months before I personally witnessed a rollback.

Facilitator: we have a red card. Number 3.

Attendee no 3: What is a rollback?

Speaker: A rollback is, when the backup is restored. In this particular case also the old system was reinstalled.

Facilitator: we have a yellow card. Is it about the rollback? Okay. Number 17 go ahead.

Attendee no 17: Do you need to test it? The system, which was rolled back.

Speaker: Of course

Facilitator: There are no more yellow cards on the stack. I’ve got green cards from 54, 65, and 78. So number 54, you can ask your question.

Attendee no 54: Which format did you use for the Deployment Plan?

Speaker: I asked and got permission from one of the suppliers to use their Deployment Plan as a starting point. The advantage was, that it was familiar to the employees of this supplier.

Facilitator: I’ve got green cards from 65 and 78. So number 65.

Attendee no 65: Why do you call it an emergency? Nobody got hurt.

Speaker: How do you call a situation with a person cutting someone’s tent? And what would happen, if this person is caught in the act?
How do you call a situation with a system, which cannot be used right after the deployment?

Attendee no 65: [nods]

Facilitator: I’ve got green cards from numbers 78, 95 and 24. Number 78, you can ask your question.

Attendee no 78: Looking at your technical background it seems easy to be a chairman. Do you know everything?

Speaker: I do not know everything. I cannot know everything.

Attendee no 78: Did you not feel vulnerable?

Speaker: At certain points of the meeting I was vulnerable. Quite vulnerable. But I was also confident, that we could make a deployment plan as a group. Sometimes I had to ask for support and I got it.

Facilitator: No yellow cards. Number 95.

Attendee no 95: So technical knowledge and experience are not necessary?

Speaker: The important thing is to have a safe environment. A place, where people can voice their thoughts.
In order to discuss all actions I chose a business way of meeting. Please stick to facts. And we’re all here to accomplish something like a group.
I watched for body language. If I was not sure, then I stated the action, looked to the person and became silent.

Facilitator: I’ve got green cards from numbers 24, 38, and 23. Number 24, you can ask your question.

Attendee no 24: You added a new blog category: A leader ships. Did you ship? A Deployment Plan is just an artifact.

Speaker: I once read something along the line like System must solve the problem. If the deployment is bad, even the best system cannot solve a problem.

Facilitator: I’ve got green cards from numbers 38 and 23. Number 38, you can ask your question.

Attendee no 38: What have juggling and testing in common? You are talking about a hobby and job. These are two separate things for me.

Speaker: I have question in return: would you please summarise both stories in 4 words?

Attendee no 38: What about: good planning withstands emergency.

Speaker: So you plan the emergency?

Attendee no 38: I need some What If Scenarios, if things go wrong.

Speaker: So you want to make a scenario for every possible situation like overloaded network, a comet paying a visit, etcetera. There are a lot of scenarios to ponder upon. I suggest: Plan to anticipate emergency. In this case: complete rollback.

In Case Of Emergency Press 1

[Note from the author: after some fact checking I discovered that I used the Red Card in a wrong way in this blog post. The red card must be used to raise issue like low volume or high temperature in the room, which can lower the quality of the gathering of information. For normal interruptions the yellow card should be used.

This basically means that I had to rewrite the blog post on certain points. This task was more complex than I had expected. The whole flow of arguments had to be restructured while preserving the spirit of this post. So I only added this note.]

Speaker: Welcome to my writing “In Case Of Emergency Press 1”. My name is Han Toan Lim. I want to share some stories with you.

Facilitator: There is an opportunity to ask questions using K-cards. More information can be found here.

Speaker: In the weeks after the Dutch Juggling Convention in 1992 a new story circulated in the Dutch juggling community. During the Public Show some people had paid an undesirable visit to the camping site. There were no guards.
“Right after the convention I would be camping. The convention [in Delft] looked like a good rehearsal, then someone made some cuts in my tent.”, a juggler told me with a bit of disappointment.
Another juggler was really upset:
“They took my knife from my tent.”
Somehow this unwanted visit was not anticipated. Over the years the story was shared less and less, but it still stung me.

Now it is time for a flash forward. Several projects were weeks from the deployment. I had pressed for a meeting and finally my project manager had agreed. During the preparation of this meeting I had merged 3 Deployment Plans of the three systems on the same day. I had still doubts about the completeness of this resulting plan. All suppliers and other involved parties of the client were present. I was the chairman.

I began with stating the goal of the meeting: everyone should know, what and when they should do in order to deploy 3 systems on the same day. On the screen I showed a gantt chart made in a spreadsheet program. It was an updated version of the team lead of system administration. The time blocks for the deployments of each system was shown. Other time blocks were for preparation and wrap ups. Then it was time to go one level deeper. On the screen the latest version of the Deployment Plan was shown by me in a spreadsheet. The first activities took me some time to let the attendees make themselves familiar with the structure of the plan.

Facilitator: We’ve got a red card.
Attendee 95: What do you mean with “make themselves familiar” with the Deployment Plan?
Speaker: The Deployment Plan was a big table in a spreadsheet. So the size could distract the reader. So I first explained the heading from left to right. Then I went slowly through the first action. So the attendees could listen or read the information with enough time for reflection. Does this answer your question?
Attendee 95: Yes
Facilitator: I see no more red cards. So you can continue.

Speaker: The following pattern arised. I read the action aloud and made sure, that the person, who was assigned the task, fully understood the task. I questioned or let it questioned in different ways:

  • Do you really understand this action?
  • Are other actions needed?
  • Are the actions planned in the right order?

I preferred, that other participants voiced their thoughts. This was beneficial for the group interaction. It was not my one man show after all.

Let me focus on one particular action, restoring the backup. If the deployment would be stopped, then a rollback of the old systems had to take place. So a backup should be restored. But it takes a while to make a good one. To be more precisely one working day. So people had to be instructed, that the systems could only be used for retrieving information and not for storing new information. Some of these actions had not been planned in.

Because no abstract actions had to be discussed, it was relatively easy to describe the specific actions. If there was agreement about the action, then I immediately updated the deployment plan on the screen. If the description of the action was still ambiguous, then people had the opportunity to clarify it.

Then came the part of the failed deployment. Some attendees were reluctant to talk about it. There might be different reasons: the actual steps for a successful deployment were discussed in depth, so they probably would not be needed. Another guess of mine was, that after 2 hours of meeting people were tired.

Afterwards I got the compliment: “You did well.”

This writing I would like to end with a Lesson Used. So time for a flashback.

In 2002 I went to one of the organisers of the Dutch Juggling Convention in Amsterdam. He told me:
“I’ve got some flowers for you.”
Before I could digest the information, he continued with:
“Right after the Public Show we asked the volunteer coordinators on stage. We called Nienke [and gave her flowers].”
Then I said:
“The other volunteer coordinator is Han Toan Lim. He is not here. He’s watching the camping site.”
He waited a moment.
“They gave you the biggest round of applause.”
At that moment I was just relieved, that no bad things had taken place at the convention’s camping site.

I thank for your attention.

Facilitator: You can ask questions using this form. I have already 4 green cards.

Losing gracefully

“Han Toan, something has to be tested.”
I got a short briefing, csv files and decent specifications. A senior tester and I had to test an interface. He started sprinting: opening a csv file and logging bugs. I froze. No time for writing test cases and reviewing them. I confessed to the tester, that I was uncomfortable with the situation. I tested a csv file, but I was losing gracefully.

Theory and practice revisited

The following text is translation of a text I found in a Dutch farm:

“Theory is: if one knows everything and nothing is right.

Practice is: if everything functions and nobody knows why.

In this company theory and practice are combined.

Nothing is right and nobody knows why.”

Learning to win

One evening I was playing Skip-Bo with my wife. My plan was to lose gracefully. So I forced myself to play the wrong cards. Her position in the game improved gradually. She was happy, so was I.

After a while I was holding too many good cards in my hand. There was no way, that I could hide them for long. I would either win or lose awkwardly. The last option was worse than the first one.

In the months after this clumsy situation I tried to repeat the steps during other games. What was the first wrong move I made? What were my following strange steps? Based on my observations I was able to extract a single rule to win or heuristic.

I think, that I might be able to find scientific evidence for my heuristic. But I chose not to, because it worked. That was my goal.

No log in required
During an afternoon session James Bach told about testing without scripts. He was in a hotel lobby and saw a computer. He described the techniques and heuristics he used to get access to this computer. At the end he succeeded.  

I was in the library. Killing my time with browsing newspaper articles. But that was not exciting after a while. I had an appointment within half an hour. In the meantime there should be something to be tested. I was still staring at the computer, when I remembered the story of James.

The computer environment had 2 access levels for normal users. A guest could use only basic functions, which were also limited. I did not have a library subscription, which would grant me a time slot to use standard office software and the browser. I could buy a time slot, but that would lower the challenge.

So I started testing the applications. There were many search engines for news and books. Then I noticed, that I could open the browser. It did not take me much time to go the download area. A document with Resume in the title drew my attention. I expected an error message, when I would attempt to open the file.

Then I actually opened the file. I had access to Word. And to personal data like name, address, birth day, …. I got more information than I had anticipated.

It was time to inform the information desk about this particular situation. One of the women acted adequately:
“Did you log in?”
“No. I did not log in.”
One brief look on the computer screen made her check the other computers in the library. She asked me the steps to reproduce the error. After my answer she continued with:
“After logging out the cache should be cleared. I’ll contact the system administrator about this situation. ”

I went back to the computer, which still showed the resume. I closed it. Then I noticed, that a pdf reader had been installed on the PC. One of the recently opened files contained passport in the name. One click gave me a high resolution full colour scan of a passport including social security number and picture of a fellow citizen.

I had made a little start. To explore in unknown environment. Without a script.

Sharing knowledge about testing and other things on my mind
