Fault Identification Strategies [00071]
EventDASIA 2009
Date26 May 2009 - 29 May 2009
LocationIstanbul, Turkey

Various strategies for fault identification exist - e.g. based on formal analysis of code or on testing - of which each focuses on certain identification aspects and fault types. This paper characterises the strengths and weaknesses of methods – in theory and practice - focusing on application-independent identification strategies, and it suggests strategies to maximise the number of detected faults while minimising the related effort. Fault activation conditions are discussed in detail, resulting in an extended scope on stimulation needs. In particular, the contribution of automation in raising the activation probabilities is investigated. Various examples of fault activation mechanisms and statistics on fault types vs. identification methods are provided as observed in practice. An interesting result is the identification of application-dependent test cases by application-independent test strategies.

Automated Verification of Code Generated from Models: Comparing Specifications with Observations [00070]
EventDASIA 2008
Date27 May 2008 - 30 May 2008
LocationPalma de Mallorca, Spain

Certification is based on compliance of the code of the code generator with given standards. Such compliance never can guarantee correctness of the whole chain through transformation down to the environment for execution, though the belief is that certification implies well-formed code at a reduced fault rate.

The approach presented here goes a direction different from manual certification.. It is guided by the idea of automated proof: each time code is generated from a model the properties of the code when being executed in its environment are compared with the properties specified in the model. This allows to conclude on the correctness of the whole chain for every application and related generated code.

Can We Provide Better Protection against Budget Overruns of Software Projects? [00069]
EventDASIA 2004
Date28 Jun 2004 - 1 Jul 2004
LocationNice, France
This paper was presented at the DASIA 2004 conference in Nice, France. The answer to this hypothetic question is "yes", of course. The paper will approach the problem in two steps: firstly, we will discuss if and which measures exist to identify an overrun early enough, secondly, we will analyse the sources of overruns and which means may be applied not to exceed the planned budget.
