Agile Inceptions: 5 tips to make them more efficient

Inceptions suffer from the same problems that affect long meetings full of people:

  1. Having a lot of people in a room like your stakeholders, your team, your boss and your boss’s boss means only one thing: long discussions about opinions and points of view, without real hard data to back those opinions, which make discussions even longer. This of course means you can’t obtain much value for your product after these discussions.
  2. It’s normal to also have people connected via video-conference like Skype or Google Hangouts. It’s 2016 but we still have issues with these types of virtual meetings, specially with internet connections not being as good as they should be. This means you’ll probably have to repeat something many times in order for everyone on the other side of the screen to understand what you’re trying to communicate.
  3. Since there are so many people invited to this event, there’s probably more than one that will be late and you’ll have to do a summary of what has been discussed up to that point, only for that person, but wasting everyone else’s time.
  4. The Inceptions I’ve been to have lasted 5 consecutive days. 5 days! 5 days, with at least 10 people in the room, for 8 hours a day… that’s 400 hours of engineers, designers, project managers and executives. Are you sure you need that much capacity in order to know what product to build and set your initial backlog? Do you really need these really expensive 400 hours?

El día que aprendí a siempre tener y nunca olvidar las checklists

Hoy mi día empezó así:

Seagull Extra 300L

Pero 10 minutos después esto pasó:

Mi nuevo avión Extra 300L con recién 3 vuelos estaba completamente destruido. Alcancé a dar algunas vueltas con el avión cuando repentinamente un ala se desprende del fuselaje y un segundo después la otra ala hace lo mismo y lo que quedaba del avión cae como un piano en picada. El fuselaje de perdió completamente y el escape del motor se dobló. El resto se salvó, incluyendo las alas, motor y toda la electrónica del avión. Todo porque se me olvidó instalar los tornillos que sujetan las alas con el fuselaje.

Despues de lamentar la pérdida comencé a pensar en por qué me había olvidado de tan pequeño detalle que causó este accidente.

En mi caso no usé un checklist que me hiciera revisar todos los elementos previos al vuelo como cargar combustible, revisar baterías cargadas e instalar los tornillos de las alas, entre otros. Y entonces ¿por qué no tenía un checklist? Porque me confié. Confié en mi experiencia y en que había hecho este procedimiento decenas de veces en otros aviones.

En aviación esa es exactamente la razón porque existen los checklists. Los factores humanos son un tópico de estudio para cualquier aspirante a piloto y un tema de investigación para organizaciones relacionadas a la seguridad en la industria aérea. Los factores humanos y nuestra infinita capacidad a equivocarnos hasta en las cosas más simples han hecho que se tengan que implementar sistemas como los checklists para estar lo más seguros posibles de que no olvidamos ningún ítem como parte de algún procedimiento.

Si los pilotos de aviones de tamaño real revisan una lista de ítems a cumplir antes del despegue y aterrizaje, entonces voy a aplicar lo mismo en el aeromodelismo. La memoria es demasiado frágil y la confianza puede jugar malas pasadas.

Kindle Paperwhite: What a Great Invention!

kindle_paperwhiteIt’s no wonder that the Kindle Paperwhite is one of the best Kindles ever created by Amazon. And you can go to its official page to read all the specifications and features. In this brief post I want to share my experience with it and the reasons why I like it so much over the previous versions.

The Paperwhite is my third Kindle. I previously owned a Kindle Keyboard and a Kindle 4. This one is the best by far. Here’s why:

  1. It has a backlight so you can read at night. With all the previous Kindles you needed a lamp and that was very uncomfortable.
  2. It has no buttons and has a touch screen. This makes it so much easier to use. Turning pages by touching the screen and highlighting text with your finger instead of touching buttons is great. After using the Paperwhite it’s easy to think that it was so tedious to use the buttons with the other Kindles, especially typing or highlighting text.
  3. Because of the 2 reasons above, you can really focus on your reading and not on the device you’re holding. With the other Kindles I was still aware of the device so it distracted me a bit. The Paperwhite makes you forget about the Kindle itself and focus on the content 100%.
  4. It’s light, slim and easy to hold.
  5. The battery runs for weeks! It’s been more than 2 weeks since I bought it and I haven’t charged it yet.

I highly recommend The Kindle Paperwhite to anyone who loves reading. I still like to have physical books on my shelf, but the practicality that the Kindle Paperwhite brings just beats real paper.
