Behavioural based safety strategy

Abstract Behavioural Based Safety, or BBS, has become a topic of substantial debate as the issue has been linked to performance.This dissertation examines the modern development of the BBS philosophy in order to determine the strengths and weaknesses inherent in the concept. The evidence presented illustrates 1 Introduction1.1 BackgroundEmployee injuries have significant impact on organisations as a whole; for example, reputation, stakeholder expectations, financial implications and legislative (Orr, 2008). Organisations therefore have to look increasingly at more effective measures to control or eradicate such events. To this end historically many organisations have looked to the development and implementation of formal safety management systems in order to address this issue. Safety management systems are a formal and prescribed means of managing organisational safety and improving performance (Agnew et al, 2012). The safety management systems currently implemented within organisations generally are centred on policies, procedures, objectives, processes such as risk assessment, hazard identification the use of various safety tools such as JSA’s and the wearing of personal protective equipment, or PPE, and focus on measuring compliance against key targets and objectives. This diss ertation examines how Behaviour Based Safety, or BBS, aids in the drive to prevent accidents and boost overall employee development (Lebbon, Sigurdsson and Austin, 2012). Qatar holds the position of second smallest country in the Arabian Peninsula after the island state of Bahrain. Qatar’s population currently stands at 2.04 million of Development Planning and Statistics, 94 per cent of which are foreign nationals (Qsa.gov.qa., 2014). Of this 94 per cent the majority is low-paid migrant workers. This number is expected to rise significantly in the coming years primarily due to the coming 2020 World Cup and the need for an influx of foreign labour for the booming construction requirement associated with it (Qsa.gov.qa., 2014). These migrant workers will primarily work on critical construction projects, drastically increasing the need for an effective safety program to be in place. The country has grown in a record breaking manner in the last ten years, to become the world†™s highest per capita GDP National (Fromherz, 2013). This achievement is primarily based on the vast resources of oil and gas discovered in the country. As a consequence of this discovery, construction of mega production plants has been the main focus of development in the country. This level of construction indicates an influx of safety challenges requiring an up to date and efficient method of implementation. These projects have historically required vast numbers of multi-cultural and diverse workforces, coming from different parts of the world (Orr, 2008). This being the case there are many challenges and great difficulties in bringing about a consciousness of safe work practices and in instilling a positive safety culture (Fromherz, 2013). The recognition of the need for workplace safety publicly materialized in the work of Mr Heinrich, an Assistant Superintendent of the Engineering and Inspection Division of Travellers Insurance Company during the 1930’s and 1940â€⠄¢s (Heinrich, 1959). His position required an investigation into the high and rising rate of supervisor accident reports during the period .This report revolutionized the working world by concluding that 88% of industrial accidents were primarily caused by unsafe, possibly preventable acts (Heinrich, 1959). This transformative moment in safety strategy motivated an entire industry to introduce reform (Fogarty and Shaw, 2010). Prior to these period witnessed steadily decreasing standards of working conditions that led to the need to reform the system. Heinrich (1959) subsequently published his first book in 1931; Industrial Accident Prevention: A Scientific Approach, laying out a more systematic approach to the study of accident data. This indication of a willingness to embrace change was tempered by the overwhelming capacity that big business interests had to keep costs low, creating a volatile safety environment. The modern era has maintained that safety is significant concern for companies, often requiring a considerable fraction of their overall revenue stream (Fromherz, 2013). This drive to increase performance and reduce injury has resulted in many companies showing excellent improvement in the area of safety performance, thereby reducing cost and increasing productivity. The rationale for this research rests on assessing the potential for improvement of HSE performance in the Oil and Gas sector, specifically in the Middle East; through a means of behavioural based safety. The intention of the study is to establish the appropriateness of this hypothesis, whether as a process to be used as a standalone mechanism, or additionally, for the augmentation of an existing HSE management system. Behaviour based safety concept, or BBS, has been considered in industry worldwide for around a decade as a means to achieve a positive safety culture and an improved organizational safety performance (Mohr, 2011). An organisation’s culture can be as influential in achieving good safety results as a safety management system. The positive or negative safety culture of an organisation is directly linked to human factors and the positive behaviour of its workforce (Mohr, 2011). According to Books (1999), the largest influences on safety culture are; 1) the style and management commitment; 2) the involvement of employees; 3)training and competence; 4)ability to communicate at all levels; 5) compliance with procedures; and 6)organisational learning. The current research has affiliation with an earlier study conducted as part of the Post Graduate Diploma award (Turner, 2013). The subject of the previous research was â€Å"Safety Culture or Climate: An Appraisal of Perceptions and Scale†. This research sought to measure the health and safety, culture and climate of the researcher’s employer organisation. In this case the researcher determined that there was evidence of a positive safety culture within the XXXX Group of companies. Howeve r, this research also illustrated that this positive safety culture has not entirely achieved the expected and desired outcome of zero harm to people. All these factors in themselves do not prevent injuries from continuing to occur within the organisation. The previous study and current research focuses on the Middle East region. In particular to the varying needs and challenges faced by operations based in the region; specifically those that require the engagement of personnel from a vast array of differing backgrounds and cultures and how the principles of behavioural based safety may effectively be used to influence this specific workgroup. To facilitate understanding, it is also important to outline the distinctiveness of the location, (Qatar), the demographics of the workgroup, and the difficulties and challenges related to the management of such a work group within a safe work environment. Based on the above reasoning this affords the researcher the ideal incentive to both add ress the topic as an area of research for the required dissertation element in partial fulfilment of the requirements for the Postgraduate MSc Degree in Health, Safety & Risk Management and to make recommendations that will enable XXXX Group to continue its safety culture development journey; that is, towards a more safety aware, proactive and empowered workforce; ultimately leading to an overall improvement in the safety performance results attained1.2 Aims & ObjectivesThis dissertation research focuses on the potential for improvement of HSE performance in the Oil and Gas sector, specifically in the Middle East; through a means of behavioural based safety. It is evident from recent research that traditional methods of safety management, such as safety management systems and risk assessments, do not wholly protect employees from incidents and injuries, as such organisations are looking for an alternative approach to improve performance and eradicate injury from the workplace, there fore the aim of this project is The following aim has been developed in order to meet this goal of this research: Critically evaluate existing research into behavioural based health and safety strategies, programmes and model with a view to identify a best practice model for future implementation. Objectives: The objectives of the research are as follows: 1) To critically analyse available literature and research studies pertaining to behavioural based health and safety. 2) To ascertain employee perceptions. 3) To identify best practices and success rates of behavioural based safety programmes. 4) To evaluate performance improvement. 5) Determine an appropriate behavioural approach for Labour safety in Qatar. 1.3 Research Questions In order to fully develop this dissertation the following questions will be considered by this research: 1) What is behavioural based safety and how does it impact Qatar? 2) Which elements of the behavioural based safety process are suited for Qatar? 3) What is the best method of behavioural based safety implementation for Qatar? 4) How to assess behavioural based safety effectiveness in the workplace?1.4 Scope of this researchThis research examines safety perception and behavioural application from 2000 until 2014 in order to ascertain the best possible elemen ts for future implementation. With a national focus on Qatar this research incorporates studies conducted in similar environments and conditions internationally in order to gain insight for these research objectives.1.5 Structure of the DissertationThis dissertation will consist of an Introduction, Literature Review, Methodology and Analysis, followed by Discussion/Conclusion. 2 Literature review 2.1 Overview â€Å"BBS is about everyone’s behaviour, not just the frontline† (Agnew & Ashworth, 2012:1). 3 Methodology / Analysis 4 Discussion/Conclusion 5 References Agnew, J. 2012.

Sustainable Solutions Paper (Answering Questions) Essay

Sustainable Solutions Paper (Answering Questions) - Essay Example This indicates a challenge that the company faces in its supply chain business. This paper represents an analysis of the company using traditional strategic thinking tools. Stakeholder Identification and Value Analysis Stakeholders refer to organization, persons, or groups of persons who may be affected by a company’s decision. Customers are the main stakeholders of the company. This is because the company has a responsibility of meeting their perfume and fragrance requirements. Thus, any decision made by the company concerning the nature of the product is likely to affect the customers. The customers define the corporate-level strategy of the company. This is because customer’s satisfaction indicates `Albani’s main business. Business-level strategy is the other significant enterprise level strategy. The strategy defines the company’s competitiveness and sustainability in the perfume industry. The company’s employees have contributed to the companyà ¢â‚¬â„¢s sustainability through the creation of high quality products. The company’s lenders and promoters have also contributed to the company’s growth and sustainability by ensuring that the company has sufficient capital. Albani promoters and lenders fulfil the functional-level strategy of the business. Finally, the company has a social responsibility that is beyond making of profits. These responsibilities define the role of the organization and the basic perception of the public towards the organization. The society, which is a bigger set that contains the company’s customers represent Albani’s public image. Culture: Organizational culture refers to â€Å"a collection of values and norms within an organization which are shared by all stakeholders and they determine or control how people interact (Macmillan, 2007). According to the article, Albani’s organizational culture can be classified as â€Å"bet your company culture.† The company ’s decisions have a major impact on its customers. Thus, big decisions are taken after considering the views of all the stakeholders. For instance changing the brand name of a particular perfume will require the approval of the customers and other relevant stakeholders. Such decisions require market research that might take a long time to materialize. Integrated Concepts from Readings According to the previous documents, the success of a company depends on various factors. Each of these factors has a role to play in determining the overall nature of the company’s external or internal environment. The enterprise level strategies define the role of the business and its perception according to the society. Thus, enterprise strategies are concerned with the corporate social responsibility of the business. The company’s culture and enterprise strategies are congruent despite not been closely related. This indicates that a company might have mission statement that is not aligned to its enterprise strategies. However, the company’s vision should be congruent to its enterprise strategies. Otherwise, its vision will not be significant to its operations. General Force Analysis General forces are factors that affect all business operating in a certain industry. This indicates that the general forces define the overall business environment. General forces relate to the society and the country’

Apple Inc. Business Analysis Essay Example | Topics and Well Written Essays - 1000 words

Apple Inc. Business Analysis - Essay Example The organization’s current strengths are multi-varied. Perhaps Apple’s greatest current strength is its competitive advantages. From the earliest incarnations of Apple Computer the company sought to carve out a competitive advantage through horizontal and vertical integration that restricted external product licensing ("Apple computer, inc.," 2011). Today among Apple’s strongest products are the iPhone, iPod, iPad, and the Mac book. These elements have a strong presence in everyday recreation uses, artistic practices, and education. In addition, they are supported by Apple’s globally strong brand. Another prominent advantage is Apple’s attention to design elements. Building products from the ground up allows Apple to implement innovative design elements that create a loyal customer base. One considers the iMac released in 1998 with its eggshell design as prominently implementing this technique ("Apple computer, inc.," 2011). This design advantage al so extends into Apple’s image. Apple, Inc. increasingly cultivates an image that presents itself as the alternative choice to mainstream computer producers. This has allowed Apple to become a cultural force resulting in significant market advantage. The iPhone contains Apple’s unique operating system, allowing it significant quality advantage over competitors ("Apple -- iphone," 2011). Indeed, quality product design has become one of the driving forces of Apple’s success and has created a significant competitive barrier for outside manufacturers, such as Google (Gilbertson, 2010). One must also consider the iPhone’s competitive advantage in terms of its position in the Apple whole. In these regards, Apple has been able to leverage its competitive position in mp3 with iTunes and its compatibility with the Macintosh operating system as a means of encouraging user identification (Schramm, 2011). The Apple App Store also provides the organization with a uniqu e advantage over other smart phone suppliers. In addition, Apple’s implementation of Siri voice activation technology will surely drive an amount of future sales. Weaknesses While Apple, Inc. has a number of strengths one must consider their potential weaknesses. One of the largest questions of the organization is the extent that they can continue their current unprecedented streak of innovation and growth. Perhaps the greatest challenge in this realm of understanding considers that company founder Steve Jobs recently died; significant questions remain as to whether new CEO Tim Cook will be able to continue this past success. While the Apple App store is a highly important element in the iPhone’s success the Android Marketplace has begun developing a number of competitive applications as a means of threatening Apple’s smart phone sustainability (Wauters, 2011). In addition, Microsoft has developed a new smart phone design and will pose new challenges to Appleâ⠂¬â„¢s overarching market share. Still, the greatest weakness is that while Apple has leveraged market share through product innovation the open source models have been able to reengineer many of Apple’s innovations. While Apple has engaged in a series of patent lawsuits, notably a recent victory over HTC, the extent that this remains a viable strategy remains greatly questionable. Furthermore, Google’s position as a cornerstone of the Internet, coupled with the

Do not need a title - Assignment Example In every society, men of this [aristocratic] class will command a superior degree of respect; and if the government is so constituted as to admit but few to exercise the powers of it, it will, according to the natural course of things, be in their hands. Men in the middling class, who are qualified as representatives, will not be so anxious to be chosen as those of the first. When the number is so small, the office will be highly elevated and distinguished; the style in which the members live will probably be high; circumstances of this kind will render the place of a representative not a desirable one to sensible, substantial men, who have been used to walk in the plain and frugal paths of life†¦. A substantial yeoman, of sense and discernment, will hardly ever be chosen. From these remarks, it appears that the government will fall into the hands of the few and the great. This will be a government of oppression†¦.The great consider themselves above the common people, entitled to more respect, do not associate with them; they fancy themselves to have a right of preeminence in every thing. It has been farther, by the gentlemen in opposition [Antifederalists], observed, that a large representation is necessary to understand the interests of the people. This principle is by no means true in the extent to which the gentleman seems to carry it. I would ask, why may not a man understand the interests of thirty [thousand] as well as of twenty? It is a harsh doctrine, that men grow wicked in proportion as they improve and enlighten their minds. Experience has by no means justified us in the supposition, that there is more virtue in one class of men than in another. Look through the rich and the poor of the community; the learned and the ignorant. Where does virtue predominate? The difference indeed consists, not in the quantity but kind of vices, which are incident to the various classes; and here the advantage of character belongs to the

Robert Smithson and Ana Mendieta Essay Example | Topics and Well Written Essays - 750 words

Robert Smithson and Ana Mendieta - Essay Example The paper "Robert Smithson and Ana Mendieta" discovers the art of the two artists, Robert Smithson and Ana Mendieta. Both artists use the earth as their medium. The only difference that we can see to them is the way by which they choose the medium to present their art. Smithson in his works tends to make monumental creations. His wonderful idea about making land into a form of art motivated him to come up with the Spiral Jetty in Salt Lake Utah in 1970. Eventually he became the proponent of Earth Art or land art. He called this as a site work, wherein the mere place or location becomes the artist medium or subject. Mendieta’s approach is almost the same. She also uses the earth and other things like feather etc. as her medium. The only difference that we can see is that she does intend to make monumental creation or big work as what Smithson is doing. She is unique in her symbolic approach in visual representation. She does not concentrate in making the site as her subject and medium. She mainly incorporates herself or her body to her art. These are things that Smithson has not done with his work. Most of his concepts revolve on his conceptual ideas of making the mere place or site as a form of art. There are reasons for these differences. Ana Mendieta strives not only to present a piece of art, like what Smithson is doing. Her concept is feministic, therefore bringing her earnest idea into the mediums by which she is using. She makes a lot of symbolisms in her work than what Smithson has done.

Vicos Project (Case Analysis) Term Paper Example | Topics and Well Written Essays - 750 words

Vicos Project (Case Analysis) - Term Paper Example Gildner (2009) reveals that for the Peruvian elites had for many decades attempted to bring an indigenous population largely viewed as backwards and pre-modern into the world of modernity without success. Therefore, it was thought that Cornell Peru Project (CPP) could bring to an end this kind of development dilemma. Cornell, working in partnership with the Instituto Indigenista Peruano (Peruvian Indigenous Institute, IIP), researched both provoked and studied social change among this indigenous population at Vicos using participant intervention method (Cornell University, n.d). By improving conditions in vital areas of education, health care, and agriculture, local anthropologists sought to insulate discrete agents of change and to monitor how effective they were. The main aim of doing this was to help improve the living standards of living of Vicos inhabitants. The most practical impact of U.S modernization efforts at Vicos came about because of pushing the Peruvian indigesimo towards an integrationalist position while marginalizing more radical advocacy for agrarian reforms. Gildner (2009) notes that the researchers of CPP found themselves between indigenous communities demanding land redistribution and land owners in the rural areas seeking the maintenance of property rights. Acting as an alternative to agrarian reform, the CPP promoted a more traditional answer to the â€Å"Indian problem† aimed at cultural assimilation as well as incorporation of politics through Spanish literacy training, increased political participation and compulsory military service. Gildner (2009) argues that this â€Å"conservative wait-and-see approach† came about from the isolated and objective science intrinsic to the modernization efforts of Cornell’s team. The success of the project was also based on power. It is the power that helped th e Vicosinos achieve a wider sharing of positive values than they had under manorial regime. Wood (1975) notes that power was recognized as a key element in change and the distribution of power in the form of participation and responsibility in decision-making to people in the community. This happened to be one of the major goals of CPP according to Wood (1975). To ensure that this became successful, CPP created a decision-making power base for the entire community through the mayorales, which is a political group within the hacienda system. Wood notes that, despite the mayorales being older men and less susceptible to innovation compared to other members of the society, the project coordinators felt that it was viable to work through traditional authority group to help drive the agenda. Research conducted by Cornell University was also aimed at stimulating and promoting technological change in underdeveloped areas. Wood reveals
