Cost Management System
Sigma allows us to manage all project-base businesses, such as construction projects throw all phases ( strategic Planning, design, construction, handing over, defects liability period and operation phase), manufacturing, software, project finance, publishing, etc.
The main difference between Sigma and other systems is that Sigma is driven by a "Scheduled BoQ" (Scheduled Bill of Quantity) rather than a plan. In fact, plans are accurate only at the moment of publishing and they become quickly obsolete when a slight change occurs in the HR, requirement, or timing in addition to their non binding elements apart from the contractual milestones.
Therefore, Sigma uses the BOQ as a platform data base for its factual contractual value, as it is an integral part of the contract between the customer and the executing company and therefore it is more tangible than the plan.
Sigma administrates all payable and receivable accounts, tasks, POs, and logs for project stakeholders and controls all cost components and is capable of linking all relevant documents thus providing aspects of project management as well.
Sigma is all about what, when, who, why and how much. It continuously compares the expected values with actual ones and follows up tasks and purchase orders (PRs). In addition, it provides control on the micro level to allow users to build there own data base for future projects
Sigma differs also from an accounting system as it would assist the operation decision-making process rather than values. For example, accounting systems manage employee salaries, while Sigma manages how these salaries are divided between the different projects, tasks and sub-task. Accounting systems manage providers due, but Sigma manages where these dues are used
