First day on the job you probably, arbitrarily chose your first language or even more likely someone else chose it for you. Your path has so far been easy with what you need to do either being dictated to you by some kind of boss figure. This maybe literally your boss, a client or even market forces.
However as your career grows, you will find yourself having to make more and more decisions. Your decisions will have far reaching impact and will likely be affecting not only your but other individuals as well. As you grow into this new roles you might need some new tools in your tool set to help you deal with some tough decisions.
What makes a decision tough? The obvious answer would be a decision that has a huge impact. If you thought so, then you would be wrong. To demonstrate this, think, if you came across a person shot and wounded in the street, would the decision to take them to hospital be a tough one? Yet the impact would be huge!
So what does make a tough decision? You have yourself a tough decision when among the options there are no clear winners, one option is good in this way the other option is good in the other way.
Finding yourself in this position can be agonizing where at night you sleep having decided to go with option A and wake up feeling option B might have been a better option after all.
While there are no silver bullets, there certainly are strategies of dealing with such issues, one of which I am going to present today.
Weighted Average Decision Matrix (WADM)
WADM is decision tool that helps you break down the decision into decision factors which you can then quantify and compute to come up with an objective value of a better decision.
To work, the tool requires at least two decisions. In our case we are going to give an example of PHP frameworks.
Your team has been tasked with building a cutting edge SAAS application and you need to choose between using Phalcon with its super performance or Laravel with its expressive style. Which one will you go with?
Step 1: List out the factors
List out all the factors that are important in a framework when building your SAAS.
Step 2: Write relevant importance
On a scale of 1 – 10 write out how important each factor is in your decision
Step 3: Weight the options
For each option rate it on 1-10 on how the option fairs in that factor.
Step 4: Calculate Weighted options
For each factor multiply the relevant importance by the weight of the option. I have separated out the weight for easier computation in a spreadsheet.
Step 5: Compute the sum
Finally compute the sum of the weighted options to get your decision.
Using the WADM method, we have been able to establish that Laravel is the better option for your project.
Hopefully this technique will save you countless hours agonizing over your decisions.
