Architecture Maturity Models

Overview

Organizations that can manage change effectively are generally more successful than those that cannot. Many organizations know that they need to improve their IT-related development processes in order to successfully manage change, but don't know how. Such organizations typically either spend very little on process improvement, because they are unsure how best to proceed; or spend a lot, on a number of parallel and unfocussed efforts, to little or no avail.
Capability Maturity Models (CMMs) address this problem by providing an effective and proven method for an organization to gradually gain control over and improve its IT-related development processes. Such models provide the following benefits:
  • They describe the practices that any organization must perform in order to improve its processes.
  • They provide a yardstick against which to periodically measure improvement.
  • They constitute a proven framework within which to manage the improvement efforts.
The various practices are typically organized into five levels, each level representing an increased ability to control and manage the development environment.
An evaluation of the organization's practices against the model - called an assessment - determines the level at which the organization currently stands. It indicates the organization's maturity in the area concerned, and the practices on which the organization needs to focus in order to see the greatest improvement and the highest return on investment.
The benefits of capability maturity models are well documented for software and systems engineering. Their application to enterprise architecture has been a recent development, stimulated by the increasing interest in enterprise architecture in recent years, combined with the lack of maturity in this discipline.

ContextSwitchDeadlock was detected

Image
I have been writing an application that loads large amounts of data into the a database. The process of loading the data into the database goes through several steps requiring a considerable amount of time to complete. The long processing time is not a matter of concern from the application stand point. However, frequently the application throws a "ContextSwitchDeadlock was detected" message that says the following: Message: The CLR has been unable to transition from COM context 0x20450a0 to COM context 0x20452f0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives ...

Visual Studio setup and deployment projects

Image
This article describes the basics of Visual Studio setup and deployment projects. Subsequent articles will cover advanced topics, including more on custom actions, .NET installer classes, and how to build an upgrade for the product. Introduction Setup and deployment projects have always been a part of the Visual Studio.NET environment. Setup projects can be used to build various deployment packages, most notably Windows Installer setups packaged as MSI files. I’ll start with a basic setup that installs a C# Windows forms program and adds a shortcut to it. First, select  Setup Project , grouped under  Setup and Deployment  in the  Other Project Types  section. Choosing this will give you an empty project for adding your deployment units. With the project selected in Solution Explorer, the  View->Editor  choice gives you a selection that includes  File System  – this is where you add your files and shortcuts. Application Folder ...
