I am not convinced your team can complete the roadmap presented in 2016. Lets look at some facts here, 2 projects released in 5 months and you expect to do another 6 in 7 months? Not going to happen and I will bet 50 000 NLG on it.
With respect I don't think you have the information required to even begin to make a wild guess at how long it will take to do any of the projects involved.
Programming projects progress in man hours, they are not all equal, just because a specific project took '3 months' does not then mean that every project must now take 3 months. How many man hours is project Q going to take in relation to initial iOS or Android implementations? How can you possibly even pretend to know the answer to that if you don't even know what Project Q is so even if you had the development knowledge necessary to gauge such things you wouldn't be able too. Could it be that maybe Android and iOS combined are actually bigger projects in terms of man hours than most of the other projects combined?
The truth is as an external observer you have absolutely no idea, only those immediately involved in the development process can know this.
How many man hours did I put into iOS or Android? Was I working on them non stop for 3 months each? Or was I working on them only after hours? 4 hours a day or 1 hour a day? Or maybe I was working on them only on weekends? Maybe only on alternate weekends?
Maybe I didn't work on them at all for 2 months and then did all the work in 2 weeks?
The truth is as an external observer you have absolutely no idea, only those immediately involved in the development process can know this.
How was my availability at the start of the year? Was I maybe preoccupied with a once off life event like a wedding, something that my wife and I have been waiting 11 years to have? Could I maybe have more hours available in the latter half of the year in which I don't have any such events? Are there maybe other factors that affect man hours that are/aren't available for certain projects?
Could it be that maybe I have double or triple the amount of hours available in the second half of the ear that I did in the first half of the year?
The truth is as an external observer you have absolutely no idea, only those immediately involved in the development process can know this.
So certainly you are entitled to your opinion and can believe whatever you want to, you are welcome to your scepticism, but I myself don't think you have enough information to be saying anything at all about the matter with any conviction and that an opinion that is not based on fact is not one to which I personally would give much weight.
I think the developers - who are actually involved in the process and therefore have the necessary knowledge required to make such calls are in a better position to give a roadmap (which by the way - a roadmap is meant to represent goals and not strict deadlines) than anyone else.
