Managing large software development projects using existing management tools can be a little imprecise. An altogether softer approach has been developed as a commercial tool, enabling project managers to get inside the development process and optimise resources. The drawback with conventional software project management tools is that they are unforgiving. There isn’t a means of ascribing levels of confidence or uncertainty and, as a consequence, the resulting answers may or may not be believable. The MODIST project management tool incorporates Bayes’ Theorem on Probabilities and the notion of conditional probabilities, and enables managers to input data in the form of probability distributions and histograms.
"The four key parameters when managing a large software development project are timescale, effort available, quality level and functionality," says David Milledge of QinetiQ and MODIST coordinator. "These parameters can be determined to varying degrees of certainty. The variation in productivity of programmers, for example, measured in lines of debugged code per day, can vary by a factor of 20:1."
The use of Bayesian Networks has many benefits compared to conventional statistical modelling. Statistical modelling, for example, produces a causal assessment on likely project duration and effort required. The Bayesian Network supports both deduction and adduction, and allows managers to explore the development process by posing ’what if’ questions, working back from the desired outcome, and observing the dependencies and risk factors.

New 3-D wiring technique brings scalable quantum computers closer to reality
19.10.2016 | University of Waterloo
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
