(ACM Digital Library, 2023-01) Nagpal, Gaurav; Nagpal, Ankita; Jasti, Naga Vamsi Krishna
Business analytics are transforming every industry in modern times, and the retail sector is not an exception to this. However, the adoption of analytics among small and medium enterprises is quite limited. There is a decent amount of research that has been done in the recent past on identifying the barriers of digitalization for small and medium enterprises. But any such work is missing in the case of analytics. Also, the small retailer, in particular, has been left untouched by the existing research studies when it comes to identifying what prohibits him from the use of analytics for making business decisions. Using a scientific way of data collection from small and mid-sized retailers and from retail industry experts, this study explores why the local retailers are reluctant to use analytics in their work and what can be done to make them more comfortable with the use of analytics. The study also proposes a novel framework for adoption of data analytics and titles it “SPEFSERT Framework.”

(IEEE, 2023-02) Nagpal, Gaurav; Nagpal, Ankita; Jasti, Naga Vamsi Krishna
Covid-19 has been one of the most disruptive pandemics to date. Among the other aspects of disruption, it also disrupted the way people work in organizations. Many of the organizations surrendered their offices for good. However, there are many ill effects of these unconventional work practices also. This research study aims to explore the perception of the employees towards the adoption of Virtual and flexible work practices. The study uses a conjoint analysis approach on different possible Work Practice Profiles, that specify the nature of work (Virtual, offline, or hybrid), nature of work schedule (flexible, or fixed), nature of ownership (individual, or team), and length of working hours (8.5 hours, or 9.5 hours or 10.5 hours). The study finds that the number of working hours is the most important criterion for the employees followed by mode of work, responsibility, and work schedule.

(Taylor & Francis, 2015-05) Jasti, Naga Vamsi Krishna
Lean supply chain management (LSCM) is one of the emergent fields of research. The present study objective is to perform review on existing LSCM frameworks and proposes a new LSCM framework. The study collected 30 LSCM frameworks with the help of extensive literature survey. The sample of LSCM frameworks have been classified based on novelty of the framework, contribution of various researchers to develop LSCM framework, verification status and modes of verification methodology used by the researchers, and also the degree of standardisation of LSCM elements. The study found that many researchers have proposed novel frameworks, lack of participation of practitioners and to some extent consultants in the field of LSCM framework development. It was also found that a huge number of incoherent elements were used to propose the LSCM frameworks. The study findings will give direction to the future researchers to propose a unified LSCM framework that will help to find out the coherent set of elements in the field of LSCM frameworks. Finally, the study proposes a comprehensive LSCM framework with the help of standard elements in the field of LSCM.

Experimental Studies in Multi Stage Incremental Forming of Steel Sheets
(Elsevier, 2017) Jasti, Naga Vamsi Krishna
Incremental Sheet Forming (ISF) is a relatively new sheet metal forming process. It hasshown great diversity in its applications ranging from automotive to biomedical fields. However, the geometries having steep walls cannot bemanufactured in single stage incremental forming process due to the fact that the maximum wall angle that can be formed is limitedfor a given sheet material and thickness. This limitation can be overcome with Multi Stage Incremental Forming (MSIF) process. This paper presents some of the experimental studies in multi stage incremental forming of steel sheets to get steep wall angles.The effect of process parameters in forming cylindrical, square and spherical cups in MSIF process has been discussed.
