Dynamic Capabilities and Project Management in Small Software Firms

A small software company depends on its capability to adapt to rapid technological and other changes in its environment—its dynamic capabilities. In this paper, we argue that to evolve and maintain its dynamic capabilities a small software company must pay attention to the interaction between dynamic capabilities at different levels of the company—particularly between the project management and the company levels. We present a case study of a small software company and show how successful dynamic capabilities at the company level can affect project management in small software companies in ways which may have an adverse impact on the company’s overall dynamic capabilities. This study contributes to our understanding of the managerial challenges of small software companies by demonstrating the need to manage the interaction between adaptability and flexibility at different levels of the company

IMPROVING ISD AGILITY IN FAST-MOVING SOFTWARE ORGANIZATIONS

Fast-moving software organizations must respond quickly to changing technological options and mar-ket trends while delivering high-quality services at competitive prices. Improving agility of infor-mation systems development (ISD) may reconcile these inherent tensions, but previous research of agility predominantly focused separately on managing either the individual project or the organiza-tion. Limited research has investigated the management that ties the agility of individual projects with the company agility characterizing fast-moving organizations. This paper reports an action research study on how to improve ISD agility in a fast-moving software organization. The study maps central problems in the ISD management to direct improvements of agility. Our following intervention ad-dressed method improvements in defining types of ISD by customer relations and integrating the method with the task management tool used by the organization. The paper discusses how the action research contributes to our understanding of ISD agility in fast-moving software organizations with a framework for mapping and evaluating improvements of agility. The action research specifically points out that project managers need to attend to the company’s agility in relating to customers, that company agility links to project agility, and that this requires light method and tool support

Spaciousness on green roofs : trees and shrubs as tools

När städer förtätas blir behovet av grönytor större. Lyfts blicken uppåt finns det massvis med oanvända ytor för växtlighet, det vill säga taken. För att ge tillbaka naturen den exploaterade ytan, kan takets yta fyllas med grönska. Den vanligaste typen av gröna tak är sedumtak, dessa är vanligtvis inte till för att beträdas och ger inte rumsbildande effekter. Det finns dock en annan typ av takplanteringar som kan bidra med liknande värden som en trädgård och där olika rum kan skapas. Att anlägga växtlighet med rumsbildande effekter på tak ställer högre krav på takkonstruktionen. Den högre kostnaden som detta medför kan vara en anledning till att denna typ av gröna tak idag inte utnyttjas i större utsträckning.When cities become more densified, the need for green spaces also increases. If you look up, there are lots of unused spaces for vegetation, the roofs. To give back the exploited surface to nature, the roof can be used for vegetation. The most common type of green roofs are sedum roofs which usually aren't meant for recreational use, nor does it provide any spatial characteristics. While there are other types of green roofs that can have similar effects as a garden, where a variety of spaces can be created. To choose vegetation with more spatial characteristics for a green roof puts higher demand on the construction. The higher cost that follows can be a reason for the lack of green roofs of this type

Nerve cell damage in mammalian brain after exposure to microwaves from GSM mobile phones.

The possible risks of radio-frequency electromagnetic fields for the human body is a growing concern for our society. We have previously shown that weak pulsed microwaves give rise to a significant leakage of albumin through the blood-brain barrier. In this study we investigated whether a pathologic leakage across the blood-brain barrier might be combined with damage to the neurons. Three groups each of eight rats were exposed for 2 hr to Global System for Mobile Communications (GSM) mobile phone electromagnetic fields of different strengths. We found highly significant (p< 0.002) evidence for neuronal damage in the cortex, hippocampus, and basal ganglia in the brains of exposed rats

An Essay on the Formation of the Meditating on the Past 懷古 Poetry in Chinese Poems-mainly from Han Dynasty Period to the Six-Dynasties Period

Detta arbete är skrivet för inköpsavdelningen på enheten PGI4, representerat på Siemens Industrial Turbomachinery i Finspång (SIT), med målet att reducera kostnader genom ett förbättrat arbete med Cash Management. Då inköpt material utgör en så pass stor del av värdet på slutprodukten, nära 60 procent, inses genast vilket stort inflytande inköpsfunktionen har på företagets totala kostnader. Även om Cash Management ägnas störst fokus hos företag med likviditetsproblem, finns det mycket att vinna genom att arbeta aktivt med konceptet också i goda tider. Därmed är syftet med arbetet att; ”analysera möjligheterna för inköpsavdelningen på Siemens PGI4 att utnyttja Cash Management för att reducera de totala kostnaderna”. Längs arbetets gång har en totalkostnadsmodell tagits fram för att tydliggöra kostnaderna relaterade till inköp, och därefter har områden specifikt intressanta ur ett Cash Management-perspektiv identifierats. Utgående från dessa områden har undersökts hur dagens verksamhet ser ut på SIT samt hur andra företag hanterar liknande aktiviteter. På så vis har lösningarna tagits fram angående vad inköp på SIT bör arbeta annorlunda med, samt hur de kan nå förbättringar. Genom tydligare riktlinjer för standardkontrakt, ekonomistyrning och villkor för transporter och prognostisering kan arbetssätt inom inköp förbättras. Ett utnyttjande av kassarabatter kan ge kostnadsbesparingar motsvarande 1% av köpesumman. Rekommendationer kopplade till orderprocessen och fakturering syftar till att undvika de årliga kostnaderna på 2,4 miljoner SEK och 300 000 SEK för tidiga leveranser respektive räntefakturor. Ett utnyttjande av inköparnas kompetens inom lagerstyrning, kan resultera i sänkningar av lagernivåer genom att styra lager per leverantör

Microwave Imaging for Breast Cancer Detection:Comparison of Tomographic Imaging Algorithms using Single-Frequency and Time-Domain Data

Still more research groups are promoting microwave imaging as a viable supplement or substitution to more conventional imaging modalities. A widespread approach for microwave imaging of the breast is tomographic imaging in which one seeks to reconstruct the distributions of permittivity and conductivity in the breast. In this paper two nonlinear tomographic algorithms are compared - one is a single-frequency algorithm and the other is a time-domain algorithm

Visions of a Martian Future

As we look beyond our terrestrial boundary to a multi-planetary future for humankind, it becomes paramount to anticipate the challenges of various human factors on the most likely scenario for this future: permanent human settlement of Mars. Even if technical hurdles are circumvented to provide adequate resources for basic physiological and psychological needs, Homo sapiens will not survive on an alien planet if a dysfunctional psyche prohibits the utilization of these resources. No matter how far we soar into the stars, our psychologies for future generations will be forever tethered to the totality of our surroundings. By shaping our environment toward survival and welfare during the voyage to Mars and in a Martian colony, we indirectly shape our psyches and prepare them for a mission of unprecedented alienation and duration. Once on Mars, human factors such as leadership structure, social organization and code of conduct, group size, gender balance, developmental cycle, mobility, length of stay and the ecological settings and type and manner of subsistence, will create a novel Martian culture. The degree that settlers are severed from the Earth will affect how radically foreign this culture will be when compared with cultures on Earth
