Development of an Agile Requirements Risk Prioritization Method : A Design Science Research Study
2023
The practice of information systems development (ISD) has changed during the past two decades from very structured approaches to agile ISD methods. However, many methods available for managing requirements-related risks in the literature follow the structured way of doing ISD. If any, few methods offer solutions to prioritize requirements risks for agile ISD projects based on recognizing requirements-related risks and patterns to mitigate these. To fill this gap in the literature, we apply the design science research methodology to develop an agile requirements risk prioritization method together with industry experts (n=54) in Finland and New Zealand in a multi-year study. The method was d…
Ketterät sopimustyypit ja hinnoittelumallit julkisissa tietojärjestelmähankinnoissa
2017
Agile contracts and pricing models in public procurements of information systems. Process of public information system procurement has been overlooked in information system science. Especially empirical study of contract types and pricing models that support agile development has been neglected. The aim of this research is to fill this research gap. The research question is how agile contracts and pricing models can be applied in public procurements of information systems. This research investigates what ways and practices for implementing agile contracts and pricing models exist in public sector. The approach of this research is qualitative. The research question will be answered by analyz…
Crisis response strategies in Finland and Spain
2017
Crises are common in today's unpredictable environment rising the importance of crisis response strategies. Two societies in Europe are chosen: Finland, where trust in society is generalized to institutions, and Spain, where trust in society remains on the level of individuals. Using the results of the European Communication Monitor 2013 survey on crisis communication, we explored three hypotheses: “certain types of crises are often met with certain types of strategies,” “cultural context makes some crises more likely than others,” and “cultural context makes some response strategies more likely than others.” We find evidence for all three hypotheses and discuss our findings about perceived…
Sosiaalialan korkeakoulutettujen ammattilaisten arviot asiakastietojärjestelmistä 2020
2022
Artikkelissa tarkastellaan sosiaalialan korkeakoulutettujen ammattilaisten arvioita käyttämistään asiakastietojärjestelmistä. Artikkelissa arvioidaan Sote-tieto hyötykäyttöön strategian tavoitteiden toteutumista sosiaalialan ammattilaisten näkökulmasta ja tuotetaan tuotemerkkikohtaista tietoa käyttäjäkokemuksista kehittämisen tueksi. Artikkelin tutkimuskysymyksenä oli: Minkälaisia arvioita sosiaalialan korkeakoulutetut ammattilaiset antavat käyttämilleen asiakastietojärjestelmille vuonna 2020 käyttäjäkokemuksiinsa perustuen? Tutkimusaineistona hyödynnettiin STePS 3.0 -hankkeessa syyslokakuussa 2020 ammattiliittojen kanssa yhteistyössä kerättyä tutkimusaineistoa (n=990), josta tähän artikkel…
Sosiaalialan ammattilaiset halukkaita osallistumaan asiakastietojärjestelmien kehittämiseen – osallistumistavoissa kehitettävää
2020
Tietojärjestelmien kehittämistyön lähtökohtana tulee olla vahva ymmärrys käyttäjien tarpeista, tehtävistä sekä toimintaympäristöstä. Lisäksi suunnitteluratkaisuja tulee arvioida käyttäjien kanssa kehittämisprosessin aikana ja käyttöönoton jälkeen. Vaikka kansallisesti kohdennetaan runsaasti resursseja tietojärjestelmäpalveluiden kehittämiseen, sosiaalialalta tutkimusta aiheesta löytyy niukasti. Sosiaalialan ammattilaisten kokemuksia asiakastietojärjestelmien kehittämistyöstä kartoitettiin osana keväällä 2019 toteutettua valtakunnallisesta käyttäjäkokemuskyselyä. Kysymyksissä käsiteltiin kokemuksia yhteistyöstä tietojärjestelmätoimittajan kanssa, osallistumisesta kehittämistyöhön ja osallist…
Why open educational resources repositories fail : the contribution of quality approaches to the success of repositories
2016
Over the last two decades, millions of Open Educational Resources (OER) have become freely available for teachers and learners online. These resources are usually accessible through Learning Object Repositories (LORs), which are databases with a user interface. LORs are rarely used to their full potential and often considered as ‘failures’. Previous studies have shown that quality has a critical role in the success of information systems such as LORs. However there are no common guidelines for quality assurance approaches for LORs, nor are there studies into the contribution made by different LOR quality assurance approaches to the success of a repository. Measuring quality and success have…
3D survey in complex archaeological environments: An approach by terrestrial laser scanning
2018
Abstract. The survey of archaeological sites by appropriate geomatics technologies is an important research topic. In particular, the 3D survey by terrestrial laser scanning has become a common practice for 3D archaeological data collection. Even if terrestrial laser scanning survey is quite well established, due to the complexity of the most archaeological contexts, many issues can arise and make the survey more difficult. The aim of this work is to describe the methodology chosen for a terrestrial laser scanning survey in a complex archaeological environment according to the issues related to the particular structure of the site. The developed approach was used for the terrestrial laser s…
A VIRTUAL HUB BROKERING APPROACH FOR INTEGRATION OF HISTORICAL AND MODERN MAPS
2016
Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and th…
3D modelling of a historical building using close-range photogrammetry and remotely piloted aircraft system (RPAS)
2018
Abstract. The photogrammetric survey of architectural Cultural Heritage is a very useful and standard process in order to obtain accurate 3D data for the documentation and visualization of historical buildings. In particular, the integration of terrestrial close-range photogrammetry and Remotely Piloted Aircraft Systems (RPASs) photogrammetry allows to create accurate and reliable 3D models of buildings and to monitor their state of conservation. The use of RPASs has indeed become more popular in Cultural Heritage survey to measure and detect areas that cannot normally be covered using terrestrial photogrammetry or terrestrial laser scanner. The paper presents the results of a photogrammetr…
A2Ba: Adaptive Background Modelling for Visual Aerial Surveillance Conditions
2015
International audience; Background modelling algorithms are widely used to define a part of an image that most time remains stationary in a video. In surveillance tasks, this model helps to recognize those outlier objects in an area under monitoring. Set up a background model on mobile platforms (UAVs, intelligent cars, etc.) is a challenging task due camera motion when images are acquired. In this paper, we propose A2Ba, a robust method to support instabilities caused by aerial images fusing different information about image motion. We used frame difference as first approximation, then age of pixels is estimated. This latter gives us an invariability level of a pixel over time. Gradient di…
