“…Researches identify the need to measure developer contribution. Fernandes et al mention that performance evaluation of teams is challenging in software development projects and propose analytical model and conduct a practical case-study in context of distributed software development setting [4]. Kanij et al points that there are no well established and widely adopted performance metrics for software testers and motivate the need for a multi-faceted evaluation method for software testers.…”

Contribution and performance assessment is an established practice in organization with its sphere of influence spanning process, policy, people (client) and personnel (employee). Multiple roles in organization (for e.g. employees, project manager, hr manager etc.) view contribution and performance assessment with different perspectives and objectives. However, despite its ability to ensure growth and affluence of organization existing contribution and performance assessment practices are marred with flaws and imperfections.The objective of this work is to serve wide-ranged requirements of software maintenance professionals (in context of contribution and performance assessment) in organization by application of variegated approaches (tools, techniques, models etc.) on software repositories (Issue Tracking System, Version Control System, Source Code Repositories etc.). We study painpoints of practitioners (in context of contribution and performance assessment) and present solution approach by mining software repositories. We implement the approach on realworld data and gather insights from practitioners to validate and improve our research. In this paper, 'SamikshaUmbra' (research umbrella that circumscribe related research threads) we present approach to meet stated research objectives and viable research directions.

“…Fernandes y otros [29] presentan el Sistema SAN (Stochastic Automata Networks) para modelar y analizar equipos de desarrollo de software y así predecir su desempeño en diferentes escenarios. A partir de la definición de unas asignaciones a proyectos y la ejecución de eventos, el sistema genera una estimación de dedicación de empleados a dichos eventos y a su vez provee probables índices de desempeño.…”

“…Esto tiene que ver con la inversión en dinero, esfuerzo, tiempo y capacitación que debe hacerse. También se aprecia un nivel bajo y medio de subjetividad, debido a que algunos de los trabajos propuestos se fundamentan en modelos matemáticos, por lo tanto, se posibilita una evaluación más objetiva [22,28,29]. Desde la perspectiva del tamaño del equipo/organización se indica que los enfoques se orientan hacia medianas y grandes empresas de desarrollo de software, esto facilita tener un amplio alcance en el número de personas a evaluar.…”

This paper presents a solution procedure for reliable production lines with service times distributed according to an exponential distribution, based on a Markovian formulation with a Kronecker structured representation (sum of tensor products). Specifically, structured Markovian formalisms are used to reduce the impact of the well-known state explosion problem associated with other methods of solution. Such formalisms combined with the Kronecker representation deliver memory efficiency in storing very large models, i.e. models with more than 4 Â 10 7 states. The exact steady-state solutions of these models may be obtained using efficient existing software packages. The proposed solution procedure is illustrated with two detailed examples, and generalised with a model construction algorithm. The computed throughput for several examples of production lines with perfectly reliable machines, as well as the computational costs in terms of CPU time to solve them with PEPS2007 and GTAexpress software packages, are also presented. In effect the paper demonstrates the power of the use of the Kronecker descriptor analysis applied to the derivation of the exact solution of the particular class of production lines considered. The Kronecker descriptor methodology is well-known to analysts concerned with computer and communication systems. Introduction and literature reviewModelling formalisms are usually applied to describe real (and large) systems, capturing their behaviour and computing performance indices. A well-known modelling formalism used for this purpose is Markov chains (Stewart 1994(Stewart , 2009). Markov chain (MC) models are present in many domains such as chemistry, bioinformatics, economics and social sciences, to cite a few. MC models use simple primitives (states and transitions) to exemplify the system's evolution and operational semantics. Associated with large systems is the well-known state explosion problem which effectively limits the use of the MC model mapping formalism for such systems using traditional methods of solution.Over recent years a number of structured modelling formalisms have been proposed for the analysis of continuoustime MCs (CTMCs), taking advantage of the particular structure of the associated transition matrices.Queueing networks (Kaufman 1983) is certainly the most well-known structured formalism in the performance evaluation area. The popularity of this formalism is based on a very intuitive idea of customers passing by queues. Many extensions to this formalism have been proposed, providing solution approximations and even product-form solutions for some queueing networks (QN) models (Dallery, Liu, and Towsley 1994;Levantesi, Matta, and Tolio 2003;Bariş and Gershwin 2011). However, most real-life systems do not satisfy the necessary conditions for product-type solutions, such as finite capacity queues.The exact solution of small production lines was initiated by Hunt (1956) followed by Buzacott (1972), Gershwin and Berman (1981) and Gershwin and Schick (1981), among others.
