estimation  Estimation Inside-out Software size estimation is one of the most critical and difficult activities in the software planning process. Measuring software size goes a long way toward determining the effort, schedule, and budget required for a project. Learn how misjudging or misunderstanding the scope and size of a project can result in budget and schedule overruns, and failed deliveries that can cause total project failure. Read More...

estimation  of Software Estimation Introduction Software development has spawned an independent industry, with organizations offering software development services exclusively. As it is perhaps in the nascent stages, the processes of asking for service, offering a service, and pricing are all somewhat haphazard. Software development falls into the category of the services industry as opposed to the product industry—that is, a service is offered, and not a product. Many parallels can be drawn with similar Read More...
Productivity for Software Estimators
Presently, software estimation is considered to be an art rather than a science. At the heart of this perception is the lack of understanding of the concept of

estimation  Concerns with Software Size Estimation The present scenario in the software industry is that there are multiple units of software size measures. These units of measure include function points, use case points (UCP), object points, feature points, Internet points, test points, mark II function point analysis (FPA), lines of code (LOC), etc. There is no accepted way of converting software size from one unit of measure into another. One odd aspect of these measures is that the size of the software is Read More...
Criteria for Selecting a Software Estimation Tool
A plethora of software estimation tools are available, each claimed to be better than the others, thereby confusing prospective buyers. An effective tool ought

estimation  for Selecting a Software Estimation Tool Software development outsourcing has now become commonplace. So, it has become necessary for the outsourcer and the provider to reach an agreement about the size, development effort, cost, and development schedule of the software product being outsourced. This has caused software estimation to move from hunch-based estimation to the use of mature, research-backed estimation techniques. The process of estimation has also moved from manual estimation using Read More...

estimation  Estimation How to Go About It While many software professionals know one or more software sizing techniques—most have a reasonable understanding of function point analysis (FPA) or use case point techniques—they’re often stymied when it comes to making a real-life estimate. Learn a methodology that can help you make realistic estimates, including best- and worst-case scenarios that you can use to make pricing and delivery commitments to clients. Read More...

Buy, Build, or Somewhere Between
Whether an organization buys or builds a resource management solution depends on a number of factors, and both approaches has its pros and cons. There is

estimation  on custom development initiatives. Estimation of project duration and costs is, therefore, often speculative. Functionality must be built from scratch, and project scope and process modeling need to be completed and understood before development begins. Getting either of these wrong may result in significant overruns to timelines and budgets. Organizations on the build route also assume the risks of implementation, maintenance, and have the responsibility for keeping abreast of technological advancement Read More...
The Underbelly of Software Project Management Tools
Project management tools for software development should include a broad range of functionality. Project teams must be able to estimate the scope and duration

estimation  as schedule variance. Software estimation functionality is almost non-existent in these packages. Componentbased tracking is also absent. Task Centric Vis-à-vis Component Centric of Scheduling and tracking tools These scheduling & tracking tools are based on PERT / CPM (Program Evaluation and Review Technique / Critical Path Method). PERT came out of research background from the development of Polaris project from the US Department of Defense and is intended to handle the uncertainty inherent to the Read More...
Guidelines for Specification of Data Center Power Density
Conventional methods for specifying data center density don’t provide the guidance to assure predictable power and cooling performance for the latest IT

estimation  guideline value for density estimation. This guideline is based on the average power and cooling requirement, including clearances, experienced in existing 1N and 2N data center installations. The exact value will depend on the power and cooling architecture selected, room constraints and the guidelines provided by the system supplier. For example, in the case of the APC InfraStruXure data center system, APC provides computer aided design tools which perform this calculation for each room design. Read More...
When EDI Goes Native, Everything Falls in Sync with IQMS
IQMS''s IQ EDI module is a natively-built solution that deals with the complexities of data synchronization among EDI documents and eliminates the need for third

estimation  definition phase (such as estimation, design, and engineering) before anything can be made or bought/delivered. The major difference is that within complex engineer-to-order (ETO) or project-based companies, the product design is an integral part of production, and at times, even continues during the site installation and commissioning. In the case of repetitive, standard items, the design is typically completed and handed over the wall to manufacturing well before the production starts. Therefore, in Read More...
