Att utföra kravprioritering med kravprioriteringsmetoder - en studie om dess genomförande och hinder under

Prioritisation of software requirements is a critical part of the development of software. Whichrequirements and in which order they will be developed is one of the main tasks that requirementprioritisation supports.There are different ways that a requirement prioritisation can be used, for example alone or in agroup and with different methods.The purpose of this report is to map out how you can carry out a requirement prioritisation alonewith different types of prioritisation methods and how you solve the problems that can arise whenprioritisting requirements. This is done by documenting the use of three different types of methodsthat can be execute alone. The methods are "100-dollar test", "Ranking" and "Top-tenrequirements".To be able to prioritise requirements, you need to establish which requirements you shall prioritise.The paper retrieves this information by interviewing stakeholders in the system and analysing theresult of the interviews and the execution of the requirement prioritisation.Three problems arose during that work and I present solutions on these problems. The problemswere 1) equivalent requirements when using the "100-dollar test", 2) low differentiation gradebetween the prioritised requirements in the "100-dollar test" and 3) that the requirements that wereprioritised weren't classified before the prioritisation, which leads to inaccuracies in the resultingprioritisation.The solution to the problems that the paper presents is to increase the amount of distributable unitsin the "100-dollar test" to 1000 per requirement, suggestions of classes of the requirements andthe combination of the methods "100-dollar test" and "ranking" to bypass the equivalentrequirements.The report is written in Swedish.Nyckelord: GoTRIS, requirements retrieval, requirements analysis, Viktoria Swedish ICT,requirements prioritisation, requirements, 100-dollar test, ranking, top 10 requirements..

Betydelsen av verbal uppmuntran vid utförande av handstyrketest

The purpose of this study was to evaluate if verbal encouragement had any influence on handstrength measurements. Twenty subjects participated in the study, all women between the age of 20 and 62 years. A standardisation of testing conditions and verbal encouragement were designed. Three measurements were conducted during two days using T.K.K 5401 Grip D. First there was a trial set, and then Test 1 (without verbal encouragement) and Test 2 (with verbal encouragement) were conducted.

Anställningsformers betydelse för häla

The subject of this study was to research whether or not different forms of employment contracts had any effect on self reported health. Whether or not any difference between these forms could be explained through the use of employee health care was also a given point of interest. To achieve this, data from the national Swedish institute of health (FHI) was used, with 6465 of the 12 166 that participated in the study. Logistic regression was the primary statistical method.Initial Chi2-analyzation found no significant difference between the two main employment forms present in Sweden. However, when the variables age, sex and level of education were held constant through logistic regression, a difference of odds at 22% between the two employment forms could be identified.

Deterministisk Komprimering/Dekomprimering av Testvektorer med Hjälp av en Inbyggd Processor och Faxkodning

Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

The study aimed to examine the overall challenges that exist regarding thetesting activities within this context, and the thoughts towards the development method testdrivendevelopment (TDD). TDD emphasizes high level of test coverage and where the testprocess is well integrated with the development process. To seek answers to our question weapplied qualitative interviews with companies and respondents to try to understand the globalchallenges that are related to this work and processes. The main conclusions presented in thisstudy is that the overall challenges are involving and educating project participants in the testingprocess activities and the contributory effect test have on the end product.

Risky Travel : resenärens riskuppfattning om staden

Riskhantering inom rese- och turismnäringen där resenärens uppfattning ligger till grund för dennes köpbeslutsprocess har fått begränsat med uppmärksamhet på den akademiska arenan.Syfte: denna uppsats syftar till att studera vilka riskuppfattningar som en potentiell resenär associerar med den urbana miljön, samt hur detta fungerar som inverkansfaktor på resenärens konsumentbeteende i valet av staden som destination. Teoretiskt ramverk: en litteraturgenomgång och ett teoretiskt ramverk visar på vad som utgör det så kallade risksamhället, betydelsen av riskkategorisering diskuteras samt hur kopplingen mellan resenärens riskuppfattning och dennes köpbeslutsprocess ser ut.Metod: för att uppnå syftet har problemet angripits med ett abduktivt arbetssätt. En kombination av kvantitativ och kvalitativ metodik har applicerats. I enkätundersökningen deltog 224 inkommande resenärer till Stockholm, vilket har bearbetats statistiskt med Pearsons Chi2-test för att undersöka graden av riskuppfattning beroende på socio-demografiska faktorer. Dessutom genomfördes nio samtalsintervjuer som ledde till en tematiserad sammanställning.Empiri: genom enkätformuläret observerades att psykologiska riskuppfattningar var mest framträdande, och i samtalsintervjuerna noterades hur riskuppfattningen påverkar konsumentbeteendet.Resultat: slutsatserna som har dragits är att 1) korrelation föreligger mellan socio-demografiska faktorer och riskuppfattning, 2) stadens livsrytm fungerar som inverkansfaktor, och att 3) uppfattningen om risker präglas av subjektivitet..

Initial evaluation of the Meritas Troponin I test for measurement of equine cardiac troponin I

Cardiac troponin I (cTnI) is considered a specific and a sensitive biomarker of cardiac disease, and due to a high inter-species sequence homology; human cTnI assays can often be used in veterinary medicine. The main aim of this study was to perform an initial evaluation of a human cTnI test, the Meritas Troponin I test, for measurement of equine plasma cTnI, in order to investigate whether the test could be a possible subject for a more comprehensive validation. The hypothesis was that the test could measure equine cTnI, as there is a good homology between equine cTnI and human cTnI. The evaluation included a dilution parallelism, an intra-assay precision study and measurement of plasma cTnI healthy horses. In the dilution parallelism and the intra-assay precision study, equine plasma with previously established high cTnI concentration, according to another cTnI assay, was used. In addition, cTnI concentration was measured in plasma, collected from 19 horses, without signs of disease at physical and ECG examinations. The obtained curve in the dilution parallelism was linear, indicating that the Meritas Troponin I test can be used to measure different concentrations of equine cTnI in plasma.

Utveckling av provmetodik för HVAC på lastbil : Klimatprovning i klimatvindtunneln CD7

The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

Automatiska GUI-test : En teoretisk och praktisk studie för hållbarare test

To automate software testing is an investment, and that makes it important to have good knowledge about automation before an implementation is made. In this master thesis a study about automated testing is carried out. The study also includes a closer look at the testing tool TestComplete. TestComplete is one out of many tools on the market that is developed for automated GUI testing and the goal is to get a picture of how well the tool can adjust to CC Systems own applications. Studies show that it is hard to write lasting test scripts.
