The main goal of project control is to identify project opportunities or problems during project execution, such that corrective actions can be taken to bring the project in danger back on track when necessary. In this study, we define different scenarios to allocate the limited budget used for the cost of activity execution, delays, and corrective actions, according to the timing and amount of the budget release. A large computational experiment is conducted on real-life project data to evaluate the performance of each scenario. The results show that both the timing and amount of the budget release have an effect on project performance.

Agile methodologies changed the way of software development in the last decades. However, there is still struggling with the implementation of agile methods in environments such as the telecommunications industry with its long lasting projects in complex and large system set-ups. In this paper, we present a survey on agile software projects in telecommunications and comparable organizations and a case study of a multi-year software integration project and its transition from traditional project execution to agile methods at an Austrian mobile network operator. Including all pitfalls and failures.

The design of the electrical part of switchgear substations is mainly carried out without taking into account the economic components and projects in this case must comply only with regulatory documents. The exclusion of economic factors from consideration when designing switchgears for substations is also due to the lack of time for a design engineer involved in the development of large-scale project documentation, and additional calculations under the conditions suitable for the end of the project execution period completely exclude the possibility of integrated accounting of all factors when choosing a switchgear circuit. The paper provides a description of the algorithm for selecting the appropriate option for the layout of an open distribution device for substations of 35-220 kV. The algorithm is based on the method of direct enumeration according to the criterion of the minimum reduced costs for the construction, repair and operation of the switchgear of substations. Possible variants of substation switchgear schemes and layouts are determined on the basis of the requirements of regulatory documents and ensure the required reliability, economy and safety. As the initial data for the determination of capital investments in the construction of electrical installations, the enlarged cost indicators are used. The algorithm is implemented in the original software "ORU CAD". The reported study was funded by RFBR according to the research project № 1837-00115.

Many organisations have adopted outsourcing for delivering critical IT services to their clients. Organisations need to identify the potential security threats of outsourced IT projects as early as possible to avoid or mitigate security incidents. Existing threat classification approaches suffer from limitations such as the lack of exhaustive threat classification criteria. In this paper, we propose a threat classification approach for outsourced IT projects. This approach aims to allow organisations to identify, minimise, mitigate, or eliminate security threats at the early stages of project execution.

Onshore access to offshore field information is critical for making safe and economical operational decisions. Disorganized collation of information can be a significant impediment to full situational understanding and can be time consuming for decision makers. Sifting through disparate sources of public Meteorological and Oceanographic (MetOcean) data; maintaining email correspondence with various offshore project members; reviewing Daily Progress Reports with stale vessel information; awaiting screen shots of ROV footage to be transmitted; all these important activities cause delays to having an updated, comprehensive awareness of the project status, asset position, or environmental conditions.

The increasing scope of electrical equipment in an offshore facility without turbo-driven End-Users has a known impact on the design of such facilities that has been discussed in the recent years [1]. The intent of this paper is to recall the historical events and present the specificities of such project execution from Vendor delivery (equipment FAT) until start-up of the facility (first oil and ramp-up). As such project is executed in many locations changing throughout time, from Vendor to yard, then towing to offshore, we will review splitting and sequencing of testing activities at the various locations and phases of project execution. A selection of the different issues encountered and solutions implemented eventually, will be covered with highlights on the priorities leading to the decisions which were taken. Feedbacks and lessons learned from designing, commissioning, operation and maintenance team perspective will be discussed in order to propose future roadmaps’ items for the industry.

In this paper, a web-based online cooperation training scheme, which utilizes the google online services and applications as students' collaborative learning environment training materials for vocational high school's project-based learning courses is presented. As a result, students can learn how to collaborate a project by google on-line services that can be more efficient achievement in all project execution stages. compared to traditional project-based learning course, the experimental results showed that the proposed scheme can reduce about 25% time with more efficient related data and document integration.

In this paper, Criticality Indexes of activities in GERT network are defined as ratios of the relative change extent of project characteristics to the relative variation degree of activities' parameters. Monte-Carlo simulation method is utilized to solve GERT network and based on this method the procedure to calculate Criticality Indexes of activities is derived. A practical RaD project is used to illustrate the results of this paper. The Criticality Indexes of the activities of the project are calculated and their variation curves are depicted. Based on the results, the managers may find the activities which influence the project makespan more evidently and thus need to be paid more attention to in the course of the project execution. In addition, the results can provide useful guidance for the project managers to take effective control measures as well.

Project execution modes describe the set of possible alternatives in which the project can be performed by a group of agents with multiple skills and different performance levels. In this paper, we present a formalized model for automatically generating the project execution modes. Based on this model, an algorithm is described for finding the set of possible agents' coalitions to perform the project. Experiments are presented showing the potential of our approach.

This paper highlights some of the work undertaken to assess transmission cable assets and explore up-rating opportunities of two 230 kV self-contained fluid-filled (SCFF) cable circuits within the British Columbia Transmission Corporation (BCTC) Network. It highlights all the work that was undertaken as part of the condition assessment studies for these cable systems. A systematic study was undertaken to examine the issues that could potentially affect all or some of the dielectric, chemical, or thermal performance aspects of the cable system. Historical maintenance data that was available on these assets were carefully examined. Following this comprehensive review a series of the "gaps in knowledge" were identified. A systematic program was developed to help fill such "gaps in knowledge". As an example, sampling ports were installed on several normal and stop joints along this cable corridor to ascertain both gas-in-fluid concentrations (DGA) and fluid dissipation factor (DF) measurements. Sheath bonding studies were performed to compare the predicted and measured bond currents and determine potential causes for these observed anomalies. This paper provides some of the results obtained to date, some of the remedial measures adopted and some of the challenges that were encountered during the course of project execution; some the observations included (a) high sheath currents (b) higher than normal concentrations of acetylene and hydrogen in dissolved gas in fluid analyses. It also focuses on some of the measures adopted and the successes and challenges that they presented. A discussion on data obtained with preliminary modifications to the sheath bonding design provided very encouraging results but it also presented some challenges.

Capacitor commutated converter (CCC) technology has been selected for several recent projects due to its suitability for application in relatively weak network locations. The modular design of CCC converters permits shorter project execution time. This paper describes the CCC technology used for the rapid city HVDC back-to-back tie

The Australian defence organisation is facing unprecedented challenges in dealing with changing strategic circumstances, the impact of the network-centric warfare, and the increasing cost and complexity of military materiel. The response to these challenges is to seek more structured approaches in defence strategic planning, capability development, and project execution. This work describes how modern systems engineering is being tailored to fulfill this need.
