To Increase Productivity, Avoid Multitasking

Most people look for ways to increase their productivity. Many of them believe that they will be more productive by handling several tasks simultaneously, what is known as “multitasking”. But this is actually a trap! By trying to perform many tasks in parallel we just lose our focus and reduce the quality of our work. To be more productive we should actually avoid multitasking!

Digital Nomads: The Upside of Being Always Connected and Working from Anywhere

Today lots of people complain about being always connected to work. A recent study shows that:

  • 45 percent of workers feel obligated to respond to emails after hours.
  • 42 percent of employees feel obligated to check in with work while on vacation.
  • 47 percent feel guilty if they don’t work when sick, either on site or from home.

This situation certainly has many disadvantages, including the increase in work-related stress and the reduction of leisure time people spend with their family and friends. However I think each person has also the opportunity to enjoy the advantages of being always connected and able to work from anywhere.

The extreme example are the Digital Nomads, people who travel while they continue to work with clients or employers. They are able to visit new places and learn about other cultures and lifestyles, as if they were tourists, while at the same time they continue working remotely an making money.

But it is also possible to be a Digital Nomad part of our time. In the same way that we can travel for a business-related conference and enjoy our free time for tourism, we can travel mostly for tourism and enjoy some of our time to do work, without feeling guilty.

It may be very nice also to work near our home instead of working from home. We can work from places that inspire us, such as a beach, a park, a restaurant with a nice view or even a beautiful library. Such changes in environment probably have a positive impact in our creativity.

So I suggest this as a new-year-resolution for 2018: instead of complaining about being always connected to work, let’s find new ways to feel better while working remotely.

Happy New Year!

Temporary Solutions: Technical Debt in Pictures

Software developers are constantly told that they should avoid Technical Debt. But very frequently it is difficult to resist the temptation. Why not implement a good-enough temporary solution that satisfies all the functional requirements? The main problem is that very often this solution ignores completely the non-functional requirements. It is not efficient, nor robust, nor maintainable, nor scalable. I think this problem may be very nicely illustrated with the pictures below.

Car Dashboard1) Functional requirement:

The dashboard must have a knob to control the air-conditioning.




car window cleaner2) Functional requirement:

The back-window must have a wiper.




lock3) Functional requirement:

The door must have a lock.




mirror4) Functional requirement:

The car must have a side-mirror.





tire5) Functional requirement:

The car must have four tires.

Sharing Some Bits of Wisdom

Sometimes I find some amazing content on the Web which I want to share with all the readers of my blog. The picture below was created by Anna Vital, and I think it presents in a very concise form some amazing bits of wisdom. It reminds us the importance of our attitude when dealing with challenges. Enjoy!

Hilarious: the Disasters Caused by Emergent Design in Practice

Several people in the Agile community believe in Emergent Design. But I think that it has caused many disasters in software development projects. See below some hilarious pictures of Emergent Design in practice, with fictional conversations illustrating the kind of thinking that generated them…

stairs1) Commenting-Out

PM: Look, the requirements were changed, we will have to modify these stairs.

Dev: It will be too difficult to modify them, I will simply write new ones.

PM: So will you delete the previous ones?

Dev: No need to delete, I will comment them out, they may be useful in the future.

up and down2) Connecting Modules

PM: You designed the stairs between floors, but you did not design the connection between stairs.

Dev: This should not be a problem, after having the stairs it is very easy to connect between them.



3) Adding New Features

PM: There is a very wide space here, I think we should add some benches.

Dev: No problem, benches are very modular, I can easily plug them here.



flow4) Emergent Design

PM: You have designed the floors, but you did not design the stairs connecting them.

Dev: Don’t worry, after we have the floors it is very easy to add the stairs.





angular5) Partial Requirements

PM: Sincerely, I am not sure that the system you implemented is what the customer expected…

Dev: You can check the requirements, our system satisfies perfectly all the customer requirements.





responsive6) Choosing a Platform

PM: Ideally this system should be built on top of a land-based platform.

Dev: Land is too expensive, I suggest we use old tires instead.

PM: Are you sure that old tires would be a good technology choice for this project?

Dev: No doubt, old tires are cheap, very modular and can be combined in multiple ways.

interface7) Cross-Cutting Concerns

PM: I see in your design that there is some coupling between the building columns and the passage.

Dev: This should not be a concern, both can perform their function despite this small coupling.

On Success and Failures

When you see a successful person, it is very easy to say that this person was “lucky”. But real success always comes after multiple failures. And the only real failure is to stop trying before you reach success. We must always keep trying!


After many years working for big corporations, I decided to create my own startup company. KashKlik is an Influencer Marketing platform with a unique pay-per-click model. Our marketplace is fully-functional, has initial revenue and already reaches millions of people globally.

Now it’s time for KashKlik to grow fast and we are looking for private investors. We just started a crowdfunding campaign in which you can participate and become a shareholder. You will find our business plan and lots of additional information here:

Looking forward to having you as a partner at KashKlik!

Workshop on Software Architecture for Agile Development

Last month I gave a workshop about Software Architecture for Agile Development, organized by ILTAM. It was very interesting, I was really pleased that the audience was engaged and asked many good questions. These workshops are an opportunity for me to meet other professionals working on different industries and exchange experiences. They are the ones who paid to participate, but I also learned from them.

Summary: This workshop will be dedicated to the topic of Software Architecture in the context of Agile Development. We will answer the question: “How much Design Up Front should be done in an Agile project?” Hayim will present his approach of Adaptable Design Up Front (ADUF), describing its rationale, applications in practice and comparison to other approaches such as Emergent Design. He will explain why adaptability is essential for the development of complex software systems using Agile methods. The concepts will be illustrated through practical software architecture approaches such as micro-services and examples of real software systems that were developed in the past. The workshop will also include an exercise on the definition and evolution of the design of an interesting system.

These are the slides of my workshop:

Below are some pictures of the audience during their exercise:
