Dependency Management In A Large Agile Environment. { End Bracket }: Dependency Management. { End Bracket } Dependency Management Eric N. Bush The many layers of dependencies in today’s complex projects create plenty of opportunities for collaboration. Unfortunately, there are often no guidelines in place for facilitating this cross-group collaborative work. Dependency management, in which one group provides a software component to be utilized by others, is one key area where collaboration skills play an important role.
The concept of dependencies is controversial among developers. Another roadblock is the "not invented here" syndrome. Despite these concerns, dependency management can have enormous benefits if handled properly and integrated wisely into your project. I recently participated in a project where one of the features required files to be downloaded across the Internet in the background so as to not disrupt ongoing critical processes. Dependency-taking requires clear communication, however. Authority Who makes what decisions? Eric N. Dependency (project management) In a project network , a is a link amongst a project 's terminal elements . There are four kinds of dependencies with respect to ordering terminal elements (in order of decreasing frequency of use): Finish to start (FS) Finish to finish (FF) Start to start (SS).
Start to finish (SF) Finish-to-start is considered a "natural dependency" whereas all the others are constraints imposed by the scheduler to reflect resource constraints or preferential dependencies. SF is rarely used, and should generally be avoided. There are three kinds of dependencies with respect to the reason for the existence of dependency: Causal (logical) Resource constraints Discretionary (preferential) Early critical path -derived schedules often reflected only on causal (logical) or discretionary (preferential) dependencies because the assumption was that resources would be available or could be made available.
In addition, these dependencies can be modified by leads, and lags. Dependency structure matrix Project network. Dependency Management - Teams WIT Tools. Microsoft is a big place with a huge number of software products in development and a number of those products have dependencies between each other. We've got a pretty rich & consistent process for managing bug across divisions -- but managing software product dependencies (e.g. The Office team needs a component from Windows in order to ship) is a different story. Some teams have built custom tools, some teams use Word documents and yet others use Excel. The common theme about the process and the tool is that two teams are essentially creating a "contract" between them. It is certainly from the task-level dependencies that you'd often see in a Microsoft Project plan.
We've recently started managing dependencies more formally within Team System, so that the different product units (e.g. Some of the interesting fields: The state flow is pretty simple: The dependency starts off in Proposed and only needs Title to be filled out.

Up one level Change management relates all the internal and external factors that influence project changes.
It seeks to forecast possible changes; identify changes that have already occurred; plan preventive impacts; and coordinate changes across the entire project. Change and Dependency Management: Changes are inevitable in construction projects and are likely to occur from different sources, at any stage of a project, and with considerable impacts. Based on time, change could be anticipated or emergent, proactive or reactive, or pre-fixity or post-fixity. Based on need, change could be elective or required, discretionary or nondiscretionary, or preferential or regulatory. Based on impact, change could be beneficial, neutral or disruptive.

Introduction to the Dependency Mechanism. Dependency management is one of the features of Maven that is best known to users and is one of the areas where Maven excels. There is not much difficulty in managing dependencies for a single a project, but when you start getting into dealing with multi-module projects and applications that consist of tens or hundreds of modules this is where Maven can help you a great deal in maintaining a high degree of control and stability. Transitive Dependencies Transitive dependencies are a new feature in Maven 2.0. This allows you to avoid needing to discover and specify the libraries that your own dependencies require, and including them automatically. This feature is facilitated by reading the project files of your dependencies from the remote repositories specified. In general, all dependencies of those projects are used in your project, as are any that the project inherits from its parents, or from its dependencies, and so on. Dependency Scope There are 6 scopes available: Dependency Management.
Introducing "Nanny" - a really simple dependency management tool. Dependency management in software projects is a pretty simple problem when you think about it. A tool to manage dependencies just needs to do three things: Provide a mechanism to specify the direct dependencies to a projectDownload the transitive closure of dependencies to a projectPublish packages that can be used as a dependency to other projects Some languages have good dependency management systems - for example, rubygems. Others, like Java, have tools like Maven which I would call a complex solution to a simple problem. I've seen companies do crazy things to manage their dependencies. Enter Nanny.
Nanny makes it really easy to setup an internal repository to manage dependencies between projects. Nanny is hosted at GitHub and comes with documentation to get you started in no time.
