Project management is the discipline of organizing and managing resources, so that a given project is fully completed within the constraints of scope, time and cost raised to its inception. Given the unique nature of a project, in contrast to the processes or operations of an organization, managing a project requires a different philosophy, as well as specific skills and abilities.

The project management software is a concept that describes several types of software Including scheduling, resource allocation, collaboration software, communication and documentation systems, used to help organize a complex project into different tasks and at a certain time.

One of the most common tasks in the administration is to schedule and track a series of events, the complexity of this task can vary considerably, depending on the needs of the organization concerned, for the / users / s of how to use the tool. Some common challenges include:

* Events which depend on each other in various ways.
* Human resources available to work in the various tasks.
* Uncertainties in estimates of the duration of each task.
* Task order to meet deadlines.
* Interference between multiple projects, to meet different requirements simultaneously.

The project planning software needs to provide much information to various persons, e.g., IT project management software and scrum project management to justify the time it takes to use it. Typical requirements might include:

* Task lists for people, and scheduling resource allocation
* Descriptive information about how long tasks take to be completed
* Early detection of project risks
* Information on workload, for planning holidays.
* Historical information on how projects have progressed, and in particular how it relates to the planned performance today.

The solar producers weigh their costs in terms of dollars per watt of energy produced, a formula that is a combination of the cost of producing a module and its energy efficiency.

At present the best products crystalline silicon modules can sell from $ 3 to $ 4 per watt, First Solar can sell at around of $ 2.40 per watt, a price the company expects to reduce soon. “I really have pushed the company the threshold. Said Travis Bradford, author of Solar. “They have great technology”

But First Solar does not generate the most Sumba. That notoriety belongs to venture Nanosolar, which shockeo its competitors in December when it announced that it would be profitable to sell thin-film panels at $ 1 watt. This figure is the Holy Grail sun, the point at which the solar energy is generally less expensive than coal, without the help of subsidies.

The senior manager Martin Roscheisen Nanosolar, who, like many solar kings, has roots in Silicon Valley, says he can achieve radical cost savings by directly applying an ink composed of nanoparticles. Nanosolar cells Powersheets of machines as they roll in pages of newspapers in print, on an average of several hundred feet per minute. Roscheisen, a strong Austrian says the first 18 months of production Nanosolar have already been purchased. “We share the market by 35% in the coming years,” he said. “The truth is that we can climb a lot more products for less.

Roscheisen’s competitors, to put it in a gentle way, they doubt his claims, noting that with the cost of raw material cost would be impossible to produce panels at $ 1 per watt. “Of course I doubt,” he said. “Otherwise, their model would be a joke.”
