### Agile Methodology Adoption Worldwide  
The world has suffered a lot financially at the hands of economic slowdowns, recessions, and because of the recent and ongoing COVID-19 pandemic. Like other industries, the IT industry has also felt its effects. IT companies have been forced to lay off employees and minimize costs through remote and off-campus operations. These changes in the way the IT companies operate, effects directly the quality of the software product. In this section, we provide an overview of different studies on Agile Adoption from the early times of Agile to contemporary times. All of these studies report different figures for Agile adoption worldwide. However, one thing that is commonly reported in these studies is that Agile adoption is increasing at a healthy rate and not just in software development but also in business development and management.  
An early study of ASD methodologies adoption was performed by the Cutter Consortium in 2001, the same year the Agile manifesto was put forward. In this survey, almost 200 individuals participated from different organizations in North America, Europe, Australia, India, and elsewhere [23]. Three interesting findings were reported in this study. First, many organizations said they used at least one Agile method compared to in late 2000. Second, Agile methods performed slightly better in terms of quality delivery, the company's performance, and customer satisfaction. Third, the repetitive nature of the Agile technique helped to communicate at every level with the customer, which helps in staying in constant touch with the customer and remaining updated on their changing needs.  
A few years later another study from the US and Europe [24] in 2005, showed that 14% of companies are using Agile methods, 49% of companies know about Agile methods and are interested in using them.  
Another important study was conducted from 13 February to 24 March 2014, in which 114 participants took part [25]. According to this study, 10.77% of respondents termed the effect of Agile adoption on the organization as \"Great Success\", 32.31% termed it as \"Success\", 40% termed it as \"Neither a success nor a failure\", 4.62% termed it as failure and 1.54% termed it as \"Too early to tell\".  
In a recent online survey from Hewelt and Packard (HP), of technology professionals and IT professionals [26], has reported that 16% of its respondents are using pure Agile, 51% are leaning towards it, 24% are using hybrid approaches and only 2% are using pure Waterfall. The majority of development teams and companies now adopt the technique, while the minority are using waterfall methods.  
In a survey study from digital.ai, it has been claimed that Agile adoption within software development teams have increased from 37% to a massive 86% in 2021 [27]. Similarly, another survey conducted by CertiProf [28], found that the COVID-19 pandemic in 2020 increased the adoption of distributed agile teamwork and 72% of the teams reported that they do not work in the same location. This study also reported that in comparison to 2020 the number of professionals having less than 2 years of Agile experience (42% in 2021) has shown significant growth. In 2022, 95% of developers report having fully adopted the Agile approach while in other sectors such as marketing, sales, finance, and HR it also showed growth.
