The STEM newsletter is a quarterly bulletin designed to keep you informed of the
latest developments in STEM: interesting applications, the latest features and a
series of how-does-it-work articles, together with news of forthcoming events.
A collection is a neat way to group elements and provide systematic aggregation across all results available
for those elements, and can be nested to form an element hierarchy.
We are working on a new partition concept which checks a hierarchy for completeness
and uniqueness, and enables a top-down results navigation where you can expand and drill-down into individual branches.
The interface for drawing graphs has been
streamlined in STEM 7.5 with dimensional selection as the norm, and more specific
Linear Selection of individual combinations when required.
We consider the complexities of
notation, selection and spareseness, and show that
STEM is the go-to application for handling cost allocation and controlling organisational spending at scale.
We have created a framework for modelling the IT value-chain in a web-scale
enterprise which extrapolates conventional revenue and cost modelling from the
hardware/site to value-added IaaS, PaaS and SaaS layers. This structure
can then be used to compare buy/build scenarios for delivering services
on either third-party
or in-house platform / infrastructure / physical data centres.
STEM 7.5 is finally ready! Or, more precisely, STEM 7.5 has been available to a
small group of early adopters since July 2016, and now a STEM 7.5a point release
is available as a recommended update for all users. So
what does that mean for you?
These release notes explain the evolution (including a list of 27 specific refinements), and offer
installation instructions and guidance on compatibility.
Suppose it were easier to connect results with what you can see in the Editor,
or that STEM could anticipate which results would be of most immediate interest.
Soon you will be able to display results from
the context menu for a selection of elements in the Editor.
A new Trace command will draw the most pertinent graphs
to explain the calculation flow for a series of elements.
Our 21st customer event was held on 05–06 October at King’s
College, Cambridge, UK. New and regular users alike engaged in
animated debate on two dominant themes of network virtualisation, as well as
further game-changing developments in the STEM platform.
The full proceedings of the 2016 event are now available for download.
Next year’s event will run 27–28 September 2017.
It is always easier to model the costs of physical infrastructure
than to estimate the effort involved in tasks relating to service provisioning
Our generic methodology for the calculation
structure, from tasks and hours per period to headcount and
payroll, allows you to focus on the data requirements and analysis
which is where the real learning and insights lie.
A fictional conversation between three of the most influential cloud business leaders at
Liverpool Street station in London, UK:
Jeff, Mark and Larry compare improvised techniques for forecasting and costing
data-centre roll-outs … then realise that the fast train to Cambridge departs from platform 6.
Our 21st business-modelling event featured a reference framework for
modelling the IT value-chain in a web-scale enterprise, as well as a menu of operational
tasks around SDN/NFV written on a matrix of skillsets and pay grades.
