Support to effectively manage software development

23.03.2005


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.



"With MODIST, you can set up real-life situations," says Milledge. "You might have to deliver software of a certain level of complexity with a development team of fixed size, and may need to know how long it would take to produce the software to a certain level of quality. Once the programme gets going, you can refine estimates and inputs, and the associated levels of confidence, and the outputs become progressively more precise. It makes risk assessments visible, and auditable, to the project management team."

The prototype was available fairly early on in the project lifetime, which enabled it to be trialled in fifteen different software development projects. The tool has now been commercialised and is available from one of the partners, Agena, under the name of Agena Risk. A key market is for projects that need to make optimal use of resources spread across sites, time zones, organisations, and market sectors.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
