Software Engineering

Notes prove it with code to show that your ideas actually work in practice and not just in theory Active
stakeholder participation is critical to the success of your modeling efforts because your project
stakeholders know what they want and can provide you with the feedback that you require. The
principle of assume simplicity is a supported by the practices of creating simple content by
focusing only on the aspects that you need to model and not attempting to creating a highly
detailed model, depicting models simply via use of simple notations, and using the simplest
tools to create your models. You travel light by single sourcing information, discarding temporary
models and updating models only when it hurts. Communication is enabled by displaying
models publicly, either on a wall or internal web site, through collective ownership of your
project artifacts, through applying modeling standards, and by modeling with others. Your
development efforts are greatly enhanced when you apply patterns gently. Because you often
need to integrate with other systems, including legacy databases as well as web-based services,
you will find that you need to formalize contract models with the owners of those systems. Read
this article for a better understanding of how AM’s practices fit together.
We would argue that AM is an agile approach to modeling, that at its core AM is simply a
collection of practices that reflect the principles and values shared by many experienced software
developers. With an Agile Model Driven Development (AMDD) (see Figure 5.4) approach you
typically do just enough high-level modeling at the beginning of a project to understand the
scope and potential architecture of the system, and then during development iterations you do
modeling as part of your iteration planning activities and then take a just in time (JIT) model
storming approach where you model for several minutes as a precursor to several hours of
coding.

What is MDD?
Did u know?
Model Driven Development (MDD) is an approach to software development where
extensive models are created before source code is written.
