Abstract

Purpose

The purpose of this paper is to present a model of the 24‐h software development process to help software project managers assess the profitability of a 24‐h development configuration and to select the optimal partnering sites. The model also helps the customer‐support divisions of software firms to decide which customer requests need to be performed using the 24‐h development mode.

Design/methodology/approach

This paper presents a graphical representation of the 24‐h software development process. Highlighting the importance of interaction times between two sites and the role of product‐, process‐, and site‐related factors that influence its value, the paper adopts the method of pair‐wise comparison of factors as done in the case of analytical hierarchy process and proposes a multiplicative model for its estimation. The software development time and cost are thereafter estimated by using site‐specific values of work hours, compensation package, and productivity. The approach is used to determine the economic viability of 24‐h development and make optimum site selection for a number of decision‐making situations.

Findings

The results obtained from applying the models to hypothetical, but realistic problems, with different values for site‐ and personnel‐specific factors to prove the ability of the model to be used in real‐life situations.

Research limitations/implications

The proposed model does not consider effects of factors like multiple interactions, reworks, and errors in communication.

Originality/value

A circular representation of the 24‐h software development process, the multiplicative model for estimating the length of interaction time, and the time and cost of development in such a process are the main contributions of the paper.

Abstract

Purpose

The purpose of this paper is to study sustainability of the global business model of software outsourcing with perspective of Indian vendors.

Design/methodology/approach

In order to obtain results as per the stated purpose, the authors have done an extensive literature review search in the e‐journals databases: ABI/INFORM Complete, EBSCO Business Source Complete, Emerald Management Xtra and Science Direct. Over and above these databases and journals, NASSCOM reports, survey and some books were also referred for literature review. Finally 59 references listed at the end of the paper were used for the stated purpose.

Findings

The paper studies trends in software industry and outsourcing models, which Indian vendors are offering to their global clients. Each model is evaluated analytically for its advantages and shortcomings subsequently the paper concludes by stating the need for a sustainable global business model in software outsourcing from Indian perspective.

Research limitations/implications

The paper studies business of software at a global level and subsequently narrows its focus on the models being provided by the Indian vendors. It identifies need for a sustainable model to be used by the Indian vendors; the limitation of the paper is it concludes with the need identification and is from an Indian vendor perspective. The needs identified can be further used as a basis for hypothesis formulation, questionnaire design, data survey and analysis so that blue print of the proposed model can finally emerge, also the study can be expanded to include global vendors.

Practical implications

The following paper analytically studies current trends in global business of software sourcing, and identifies pros and cons of the models adopted by Indian vendors. It identifies the need for a sustainable global business model for software outsourcing; in case the need is fulfilled it will definitely add value to India as a software sourcing destination and lead to more revenue generation which will eventually culminate into a large‐scale and long term economic and social impact. The study also has several research and public policy formulation implications.

Originality/value

The paper is completely original work of the authors where the value addition is clearly seen by studying the advantages and shortcomings of the existing models of software outsourcing adopted by Indian vendors and identifying the need for sustainability therein.

Abstract

Purpose

The purpose of this paper is to answer the question asked by Buelen “What do we still need to learn about outsourcing across time zones?”.

Design/methodology/approach

This paper serves as a response to the commentary by Erik Beulen in SOIJ Vol. 5 No. 1 titled “I'm working while they're sleeping: time zone separation challenges and solutions”.

Findings

The paper finds that we are still very much at the beginning of the “era of time zone dependent work.”

Originality/value

This futures analysis leads to the projection that many more individuals will be entering time zone dependent work. While technology may elevate some of the hardships of temporal separation, it will exacerbate others.

Abstract

Purpose

The purpose of this paper is to find good values of onsite-offshore team strength; number of hours of communication between business users and onsite team and between onsite and offshore team so as to reduce project cost and improve schedule in a global software development (GSD) environment for software development project.

Design/methodology/approach

This study employs system dynamics simulation approach to study software project characteristics in both co-located and distributed development environments. The authors consulted 14 experts from Indian software outsourcing industry during our model construction and validation.

Findings

The study results show that there is a drop in overall team productivity in outsourcing environment by considering the offshore options. But the project cost can be reduced by employing the offshore team for coding and testing work only with minimal training for imparting business knowledge. The research results show that there is a potential to save project cost by being flexible in project schedule.

Research limitations/implications

The implication of the study is that the project management team should be careful not to keep high percentage of manpower at offshore location in distributed software environment. A large offshore team can increase project cost and schedule due to higher training overhead, lower productivity and higher error proneness. In GSD, the management effort should be to keep requirement analysis and design work at onsite location and involves the offshore team in coding and testing work.

Practical implications

The software project manager can use the model results to divide the software team between onsite and offshore location during various phases of software development in distributed environment.

Originality/value

The study is novel as there is little attempt at finding the team distribution between onsite and offshore location in GSD environment.

Abstract

Purpose

This paper aims to explore the expertise level required in various kinds of business knowledge such as regulatory, domain, strategic, operation process and, business process to execute globally distributed software projects for development, re-engineering and maintenance projects in the Indian outsourcing software industry.

Design/methodology/approach

This study adopted a questionnaire survey method to collect the expert responses for a knowledge management framework which is suggested in the literature for software development work. The questionnaire survey findings were verified by expert interviews.

Findings

The research shows that there is a lot of similarity between re-engineering and maintenance projects for different kinds of business knowledge expertise requirements for execution. The development projects require higher expertise in all the business knowledge for execution.

Research limitations/implications

The research work studies the business knowledge required for the execution of development, re-engineering and maintenance projects in Indian outsourcing software projects. However, the project’s characteristics can vary drastically for a single kind of project. So the study cannot be generalized and instead should be used as a tool for learning.

Practical implications

The research findings can be used by software project managers to get insight into project planning, which can help the division of work between the onsite, offshore team and individual work allocation.

Originality/value

The research is novel as there are very few previous attempts to find the business expertise needed to execute various kinds of software projects in the Indian outsourcing industry.

Abstract

Purpose

The aim of this paper is to make an attempt to find good values of onsite–offshore team strength; number of hours of communication between business users and onsite team and between onsite and offshore team to reduce cost and improve schedule for re-engineering projects in global software development environment.

Design/methodology/approach

The system dynamics technique is used for simulation model construction and policy run experimentation. The experts from Indian software outsourcing industry were consulted for model construction, validation and analysis of policy run results in both co-located and distributed software development environment.

Findings

The study results show that there is a drop in the overall team productivity in outsourcing environment by considering the offshore options. But the project cost can be reduced by employing the offshore team for coding and testing work only with minimal training for imparting business knowledge. The research results show that there is a potential to save project cost by being flexible in project schedule.

Research limitations/implications

The study found that there could be substantial cost saving for re-engineering projects with a loss of project schedule when an appropriate onsite–offshore combination is used. The quality and productivity drop, however, were rather small for such combinations. The cost savings are high when re-engineering work is sent to offshore location entirely after completion of requirement analysis work at onsite location and providing training to offshore team in business knowledge The research findings show that there is potential to make large cost savings by being flexible in project schedule for re-engineering projects.

Practical implications

The software project manager can use the model results to divide the software team between onsite and offshore location during various phases of software development in distributed environment.

Originality/value

The study is novel as there is little attempt at finding the team distribution between onsite and offshore location in global software development environment.

Abstract

Purpose

The purpose of the paper is to find out the knowledge requirements and its effect on both onsite and offshore project work division for development, re-engineering and maintenance projects in Indian outsourcing software industry in different phases of software development.

Design/methodology/approach

This study employs an expert interview approach in Indian software industry to find out knowledge requirement for project execution and division of work between onsite and offshore locations. The requisite data were collected through expert interviews and direct observations.

Findings

The study found that the development projects require higher level of domain, strategic, business process and operation process knowledge in comparison to re-engineering and maintenance projects. So there is a need of higher onsite presence in development projects. The maintenance work is taken up at the offshore location in a phase-wise manner.

Research limitations/implications

The implication of the study is in the development of a broad framework of knowledge requirements and work division in on-shore and offshore locations for Indian software outsourcing projects. As the study is based on expert opinion in the context of India, it cannot be generalized for outsourcing scenarios elsewhere.

Practical implications

The software project manager can use the findings to get more insight into the project and divide the software team between onsite and offshore location.

Originality/value

The study is novel, as there is little attempt at finding the knowledge requirement to execute various kinds of business software development in outsourcing environment in the context of India.

Abstract

Purpose

The paper aims to study manpower dynamics at offshore and onsite location for maintenance project, which are transferred to offshore location in a phase-wise manner. The purpose of the paper is to find good values of onsite–offshore team strength, the number of hours of communication between onsite and offshore teams for smooth transfer of software maintenance project to offshore location.

Design/methodology/approach

This study uses system dynamics simulation approach to study manpower allocation at onsite and offshore locations to transfer the maintenance work to offshore location in a gradual manner. The authors consulted 13 experts from Indian software outsourcing industry during the model construction and validation.

Findings

The simulation results show that the complexity of maintenance project has an insignificant effect on offshore migration. The maintenance work transfer should start with initial onsite team strength higher than that of required for ticket solving and project. The initial offshore team strength should be based on training capacity available at the onsite location. The higher attrition rate at an offshore is detrimental for offshore migration.

Research limitations/implications

The implication of the study is in the development of a broad framework of software maintenance work transfer to offshore locations for Indian software outsourcing projects. As the study is based on expert opinion in the context of India, it cannot be generalized for outsourcing scenarios elsewhere.

Practical implications

The software project manager can use the findings to get more insight into maintenance project offshore migration and divide the software team between onsite and offshore location.

Originality/value

The study is novel as there is little attempt at finding the manpower composition at onsite and offshore locations for software maintenance project during the migration phase.

Abstract

Purpose

The purpose of this paper is to introduce a new design for a finger and wrist rehabilitation robot. Furthermore, a fuzzy sliding mode controller has been designed to control the system.

Design/methodology/approach

Following an introduction regarding the hand rehabilitation, this paper discusses the conceptual and detailed design of a novel wrist and finger rehabilitation robot. The robot provides the possibility of rehabilitating each phalanx individually which is very important in the finger rehabilitation process. Moreover, due to the model uncertainties, disturbances and chattering in the system, a fuzzy sliding mode controller design method is proposed for the robot.

Findings

With the novel design for moving the DOFs of the system, the rehabilitation for the wrist and all phalanges of fingers is done with only two actuators which are combined in one device. These features make the system a good choice for home rehabilitation. To control the robot, a fuzzy sliding mode controller has been designed for the system. The fuzzy controller does not affect the coefficient of the sliding mode controller and uses the overall error of the system to make a control signal. Thus, the dependence of the controller to the model decreases and the system is more robust. The stability of the system is proved by the Lyapunov theorem.

Originality/value

The paper provides a novel design of a hand rehabilitation robot and a controller which is used to compensate the effects of the uncertain parameters and chattering phenomenon.
