Quality assurance and performance testing service
How the quality assurance and performance testing works
We provide pro-active quality and risk management, embedding quality practices and instilling quality oriented behaviour throughout your teams

Reporting metrics for your fully automated quality assurance and performance testing enables your teams to effectively prioritise their work, and gives transparency to the improved quality over time.

We automate the monitoring of in-life performance, and when SLAs are breached to then automate actions such as scaling and the creation of tickets back into the engineering pipeline.

Where appropriate, we will show you how to actually automate deploying into a performance test environment, configuring it, and then execute an extensive performance test pack.

Fighting climate change

Fighting climate change

We have Carbon Reduction Plan, which has been completed in accordance with PPN 06/21 and associated guidance and reporting standard for Carbon Reduction Plans.

Emissions have been reported and recorded in accordance with the published reporting standard for Carbon Reduction Plans and the GHG Reporting Protocol corporate standard and uses the appropriate Government emission conversion factors for greenhouse gas company reporting.

Scope 1 and Scope 2 emissions have been reported in accordance with SECR requirements, and the required subset of Scope 3 emissions have been reported in accordance with the published reporting standard for Carbon Reduction Plans and the Corporate Value Chain (Scope 3) Standard.

The Carbon Reduction Plan has been reviewed and signed off by the board of directors (or equivalent management body).

In order to achieve this our plan, we undertake carbon-saving activities such as: Working from home rather than commuting and maintaining a fully staffed office. Use public transport rather than private. Recycle all recyclables. Fully electric company fleet. Use sustainable suppliers. Extensive use of online meetings and events.
Covid-19 recovery

Covid-19 recovery

Catapult has highly flexible working conditions. We offer employment to people who do not require an office to work in, as we utilise the latest online technology that enables us to prefer and encourage home and remote working over working from an office.

Remote working allows us to hire those left unemployed by COVID-19 from anywhere in the country; it also enables us to employ people who need to socially distance or are highly vulnerable and for them to fully participate. We find that remote working democratises our company.

As a growing technology consultancy, we are in a high growth sector, so the employment we offer is of high value for our employees. We are leaders in the use of cutting edge online tools that enable us to work remotely much more effectively.

The flexible working practices and tooling are a vital support to those people who are suffering from the physical and mental health of people affected by the covid-19 pandemic, as well as providing great opportunities for knowledge sharing and cross-company training to happen.
Tackling economic inequality

Tackling economic inequality

Catapult is a small dynamic and growing company. We are an entrepreneur-led company. We partner with micro-companies and SMEs to bolster our capacity to scale and offer specialist skills; this has been core from the start of our company and is still fundamental to the success we have today. Our micro-company supply chain provides specialist technical, security and engineering skills, and are located in parts of the United Kingdom.

We regularly hire young or disadvantaged people and provide them with training both formal, and on-the-job training, so that we foster untapped innovation that perhaps otherwise might be lost.

Our specialist areas of technology and consulting have always had skills shortages, but nonetheless we are closing the national skills gaps and creating wealth by creating more specialists. We require our micro-company supply chain to do the same, since as our customer base grows we need to scale our supply chain as well.

Widening our supply chain and hiring further staff allows us to bring in more skills and cross populate these skills between our combined team, thereby providing future-proofed commercial growth,, all the while bringing vital services to the public sector.

One example of an integrated supply chain bringing benefits is in cyber. During the initial months of the Ukraine invasion, the intensity of cyber attacks increased on one of our public sector customers. We utilised various micro and small businesses combined with two large enterprises (AWS and OKTA), to achieve less than one-hour response and mitigation to the cyber attacks. By doing this we provided influence to our public sector customer and our complete supply chain, providing both support resistance and capacity in a full end to end service wrap.
Equal opportunity

Equal opportunity

We have an Equality and Diversity Policy which is dedicated to encouraging a supportive and inclusive culture amongst the whole workforce. It is within our best interest to promote diversity and eliminate discrimination in the workplace.

We ensure that all employees and job applicants are given equal opportunity and that our organisation is representative of all sections of society. Each employee is respected and valued and able to give their best as a result.

The policy reinforces our commitment to providing equality and fairness to all in our employment and not provide less favourable facilities or treatment on the grounds of age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, ethnic origin, colour, nationality, national origin, religion or belief, or sex and sexual orientation. We are opposed to all forms of unlawful and unfair discrimination.

All employees, no matter whether they are part-time, full-time, or temporary, are treated fairly and with respect. When selecting candidates for employment, promotion, training, or any other benefit, it will be on the basis of their aptitude and ability.

Catapult are a proud member of the Living Wage Foundation, and we have always paid well above the living wage as defined by LWF.

In March 2022, we had 40% of employees identifying as Female; 50% of our company board are female. We operate a ‘blind’ recruitment process we provide internships for University students, (e.g. Durham, UCL and Bournemouth Universities). 45% of the workforce have declared that they have Black, Asian or Minority Ethnic origins.

9% of employees have declared they have a disability.

100% of our people work remotely, with flexible working hours, and advanced ergonomic workstation assessments; this encourages people who are unable to travel, leave their homes, or with home care obligations to work with us, and many do.
