How to choose the right technology / tooling in IT
Yakup Kalin @yakupkalin
I'm involved in agile mobile development, where I develop and deliver creative input for realizing
usable and likeable mobile applications.
embraced tools (tools: technology, development language, libraries, frameworks, methodologies, …)
Creating applications
And most of the time…
Developer: Why tool a, and not tool b?
Email: Did you hear about tool b, it’s very cool?!
IT Article: Tool b is better than tool a.
Business: Tool e is FREE
Explain why
Do you know why?
You should.
Do you know why JAVA?
Do you know why .NET?
Are you sure about PHP?

Developers are leading indicators of technology shifts (Forrester)
If you know what technologies are growing out in the social coding community and where developers are investing their time, it’s possible to predict what technologies might seep into the enterprise through the back door. (Forrester)
Good to know before introducing a tool…
COCOMO
The Constructive Cost Model (COCOMO)
is a software cost estimation model
It predicts the effort and schedule for a
software product development based on
inputs relating to the size of the software and
a number of cost drivers that affect
productivity
COCOMO
Basic model Intermediate model Detailed model
3 Models
Basic model
1. Quick, early, rough order of magnitude estimates of software costs
2. Does not account for differences in hardware, constraints, personnel quality and experience, ...
Introducing a specific tool not always a good idea
Software development process
Design, develop, integrate & test
Project planning, project monitoring, measurement & analysis, ….
DefinesQuality
The Capability Maturity Model (CMM) is a methodology used to develop and
refine an organization's software development process.
Introducing an innovation tool within company at ”initial” stage
Introducing tool that eliminates risk and waste
