Project Estimation

Agile estimation process is an emerging research area because of agile practice of accepting requirements at any stage. Some agile practitioners are using agile estimation of size and time based on expert opinion and planning poker game. These methods are non-algorithmic method whereas algorithmic method of estimation always useful for novice estimator as it is based on empirical study. In this paper, we have proposed algorithmic method, Priority based Agile Estimation for Size and Time (PAEST) for projects using agile practices. PAEST incorporates the identification of factors estimating size of projects based on its priority and impact on the project. Size and Time estimation are computed as function of priority factor of project attributes and uncertainty in requirements of the projects. Paper also elaborates the case studies of various domain of software projects along with priority and intensity level of factors affecting the project estimation. We have incorporated three domains: web application, MIS project and critical software and seven project attributes out of 21 attributes used by generalized estimation method in our case studies. Number of project attributes can be scalable to any number depending on project domain. Algorithm prioritizes the project attributes and generates the estimates of the project more realistic. Introduction of prioritization helps novice to get estimates more precise. In our study we observed that uncertainty in project have more impact than project attributes.

Project Estimation

Accurate estimation of software projects is quintessential for overall success of the project. Estimation of agile projects adopted in most of the modern software projects is challenging due to lack of historical data and due to dynamic characteristics of the agile projects. In this paper we introduce “Normalized Sprint Estimation” method which factors in dynamic characteristics of the agile projects such as non-functional requirements, sprint success factors and such. The author applied the normalized sprint estimation method to 14 sprints from three digital projects and the predicted estimation values had Pred (0.3), more than 80%. Though the normalized sprint estimation model is tested for digital projects, the same methodology can be applied for software projects from other domains as well.

Initial Results

This paper evaluates the effect of making a subjective decision in a design for assembly time analysis. An example is found in the first set of questions for estimating handling time of a part the user chose “parts are easy to grasp and manipulate” as opposed to “parts present handling difficulties”. The subjectivity is explored through a study of assembly time estimates generated by a class of mechanical engineering students in the time analysis of a clicker pen based on the Boothroyd and Dewhurst estimation method. The assembly times calculated by the class ranged from a minimum of 23.64 seconds to a maximum of 44.89 seconds (range of 21.25 seconds). This large range in results serves as motivation in determining the effect that answering a subjective decision has on the resulting assembly time estimate. Initial results indicate that not answering the first level of subjective questions will result in assembly time estimate within 15% of the time had the subjective question been answered. The probability density plots of the time estimates also indicates that 63% of the time, the estimated assembly time without making the subjective decision will fall within the normal distribution had the subjective decision been made. This provides evidence that there is an opportunity to reduce the amount of subjective questions that a user must answer to estimate the assembly time of a product.

The validity of an attentional model of prospective time estimation was tested in three experiments. In the first experiment two variables were manipulated: (1) nontemporal information processing load during the estimated interval, and (2) time estimation method, ie production of time simultaneously with the performance of a second task, or reproduction of time immediately upon termination of a task whose duration has to be measured. As predicted, a positive relationship between produced time length and information processing load demanded by a simultaneous task, and a negative relationship between reproduced time length and information processing load during the estimated interval, were found. The results were replicated in a second experiment in which verbal estimates of time were also measured and the objective duration of the estimated interval was varied. The pattern of results obtained for verbal estimates was similar to that obtained for reproduced ones. The results of a third experiment indicated that produced and reproduced times were positively correlated with clock time. The results are interpreted as supporting an attentional model of prospective time estimation.

Abstract The research aimed to determine the impact studied factors represented by (people’s activities, government activities, natural factors) on the deterioration of natural pastures in the Governorate of Al-Muthanna the point of view of agricultural employees in the governorate. The research included all agricultural employees with a preparatory scientific qualification in agriculture and above in the governorate their number is (94) employees. A questionnaire was prepared to collect the data necessary to achieve the objectives of the research. It consisted of two parts. The first part included the factors related to the employees, which are (term of service, academic achievement, participation in extension activities, job position and work location). The second part included a measure to identify the agricultural employees’ the point of view of on the factors affecting the deterioration of natural pastures. It consists of (46) section spread over (3) field covered by the research. The results showed that government activities have the most impact on the deterioration of natural pastures, it was found a statistically significant difference in the respondents’ point of view about the influence of the studied factors according to their personal characteristics. The researchers concluded the necessity of agricultural expansion in pasture lands and industrial investments, as well as the importance of personal factors in assigning employees who can work in the development of natural pastures, and the researchers recommend activating government laws for the protection of natural pastures to prevent abuses (people’s activities, government activities) that contributed greatly to the deterioration of vegetation cover in the research area and taking into account the factors studied in the selection of workers in the development of natural pastures in the research area.

The Relationship

There is great interest in the role of management control on theoretical and practical developments within the field of Inter-organizational Relations. This research aims to contribute at verifying how relationships between firms affect the management control tools used, as illustrated in a specific case: the relationship between the franchisor and its franchisees, which has not received much attention to date. As indicated by previous research, case studies can be helpful to determine the factors affecting the type of management control tools that should be established to manage inter-firm relationships.Results have found that the franchisor uses quantitative control mechanisms in order to avoid common types of opportunistic franchise behavior related to royalty payments and other financial requirements, as well as qualitative tools to assure the fulfilment of agreement-related conditions regarding knowhow, to resolve unexpected non-economic problems and to encourage personal relationship and trust. This study also provides an outline on franchisor-franchisee relationships in the model proposed by Van der Meer-Kooistra and Vosselman (2000). To test this model, the franchisor's perspective (outsourcer) has been taken into account as performed when building the model. Findings indicate that this relationship shows many similarities to the pattern based on bureaucracy and a few similarities to patterns based on trust.

The global population is aging in an unprecedented manner and the challenges for improving the lives of older adults are currently both a strong priority in the political and healthcare arena. In this sense, preventive measures and telemedicine have the potential to play an important role in improving the number of healthy years older adults may experience and virtual coaching is a promising research area to support this process. This paper presents COLAEVA, an interactive web application for older adult population clustering and evolution analysis. Its objective is to support caregivers in the design, validation and refinement of coaching plans adapted to specific population groups. COLAEVA enables coaching caregivers to interactively group similar older adults based on preliminary assessment data, using AI features, and to evaluate the influence of coaching plans once the final assessment is carried out for a baseline comparison. To evaluate COLAEVA, a usability test was carried out with 9 test participants obtaining an average SUS score of 71.1. Moreover, COLAEVA is available online to use and explore.

The objective of this reseach are to: (1) analyze the factors affecting human development index and household expenditures for health, education and others, (2) predict the impacts of government expenditure policy in the field of education, health, and infrastructure on human development index in Central Java. The model was built using econometric approach in the form of a system of simultaneous equations, including five blocks i.e. government's revenue, expenditures, input, output, and performance. The system of simultaneous equations consisted of 26 equations (19 structural equations and 7 identity equations). The estimation method used Two Stage Least Squares with SYSLIN procedure. Prediction simulation used the stepwise Autoregressive method. The model simulation used Newton's method and SIMNLIN procedure. The results of policy simulation concludes that the combination of the increase in government expenditure for education and infrastructure lead to better performance in increasing income per capita, disposable income and HDI compared to the combination of the policy of the increase in government expenditure for education and in both municipalities and district, but municipalities receive greatest impact compared to the district.
