The ability to use my own data in our model instead using external sources - this saves time! I prefer having all models within one platform but it can be confusing at times as there are multiple versions available (eg; you might have 1 version for analysis purposes with limited features or another which allows more flexibility). We're able solve problems faster than before because we now know how long they will take us beforehand so don't waste too much effort trying not-so important issues first then solving them later when its been found out what takes longer/costs less work etc..
