Abstract:  
INTRODUCTION We have been shot peeners for a while now. Having fully acknowledged the efficacy of the process, we have advanced it from hammer peening leaf springs in medieval times to today’s computerised shot peening of mission-critical aircraft components. Over the years, along with sophisticated machinery, we have also installed processes and specifications that ensure process reliability. We have early adopters in the automotive and aerospace industries, followed by oil & gas, mining, and medical implants embracing our cohort more recently. Though the common goal is to generate compressive stress leading to increased fatigue life, the indentations also create reservoirs that store the lubricant in certain components. Whatever the ultimate goal, clear awareness of the process and the desire to adopt are directly proportional to the user’s earnestness in conforming to commonly adopted specifications.
