Additionally, projects might have associated environmental risks. For example, a company might consider building a new state-of-the-art datacenter to cut carbon emissions, but it might conflict with overall objective to save money. A company might consider switching from desktop PCs to lower-power thin clients -- which could hinder the overall objective and reduce employee morale. These risks could also be factored in to the project's picture.
Once benefits and risks are estimated for each project, decision-makers can view all proposed projects at once and see which would best help achieve the organization's overall green goals. Projects and their associated tasks are assigned to the proper individuals and linked to appropriate data sources -- and information starts flowing in. From there, one can track the progress of the project on an ongoing basis. You can see what's been done, what's in progress, and who is responsible for which tasks. An array of reports are available for gauging progress from various perspectives.
One might find that certain projects aren't meeting overall objectives as well as one had expected and might make changes to the project -- and its ratings -- as necessary. Similarly, one might discover unforeseen risks, such as a project having more of an adverse environmental impact than expected. Alternatively, they might find a project is exceeding expectations in one way or another and adjust the rating accordingly. The company will have an accurate measurement of a project's overall impact once it's complete, data than can be applied to similar projects down the road.
Overall, I'm impressed with what I've seen of CA's ecoSoftware. Both provide a means of collecting valuable data for measuring the progress of various green projects, which is critical for realizing an organization's sustainability objectives. Other organizations offer similar tools. Microsoft, for example, announced earlier this year its Environmental Sustainability Dashboard for Dynamics AX, which enables companies to track energy consumption, greenhouse gas emissions, and other green-oriented stats. Organizations such as Tideway and Nimsoft have tools for monitoring server utilization and performance. SynapSense employs wireless sensors to monitor and map datacenter health. Additionally, plenty of companies offer carbon calculators. However, CA's ecoSoftware appears to be one of the most comprehensive green-project assessment tools I've seen to date.
