Society has developed with the implementation of ideas that have come together to create new solutions to problems or improvements to existing systems, processes, products or attempted solutions. Having ideas, implementing them, developing new ways of doing things and improving existing ways of doing things have been part of mankind’s history  . Ideas and concepts have influenced change as well as being influenced by it, reflecting through language the social understanding of the world  . The coming together of ideas and the process for developing solutions to problems has been called innovation, but what is it and how does it happen? To answer this question, we first need to understand the history of innovation. We also need to be able to define what it is and some of the definitions within the existing literature need to be examined to understand how it is understood by different sections of the academic, political and professional communities. Creativity and the development of ideas are key components within the innovation process and this research looks at the creative process. There is a significant academic literature on the creative proofs with different models and theories put forward to show how the process works. Several academic models that have been put forward during the twentieth century are examined. A well as understanding what innovation is it is important to understand how it can be applied to the world that people are living in to deliver benefits that improve people’s lives. The research looks at two studies that were carried out in England that looked at innovation within social housing providers. To provide a context within which we can focus on innovation, it is worth looking at the history of innovation briefly.
2. Innovation: History
Novation was a medieval legal term relating to “renewing an obligation by changing a contract for a new debtor”  . The term was rarely used until the twentieth century and used significantly in the early twenty first century. Godin  argues that the meaning of the term innovation in the twentieth century has been a resolution between the two contrasting terms of imitation and invention which have evolved through the centuries from ancient Greek philosophy. The imitation of reality was a central theme in the work of Plato and there has been a continuous debate throughout the centuries about art imitating, copying or being an interpretation of reality    . Imitation has been considered as invention at different points through history, during the sixteenth and seventeenth centuries in England patents were given to importers of existing inventions to stimulate economic growth instead of to inventors   and during the eighteenth century the imitation of goods produced for consumption was considered as invention for improving the quality, design and appearance of these goods    . The expansion of consumerism from the sixteenth century  together with the development of economic thought around wealth and material prosperity from the seventeenth century  provided a context within which the later industrialization processes can be said to have developed.
The renaissance in fourteenth century Europe had fostered a spirit of discovery in the following centuries to seek the new, across all fields of knowledge including the arts, science, literature, history and economics  . Scientific discovery and technological advances were allied to invention  which by the nineteenth century had become key parts of the industrialization process linked to the economics of profit which in turn impacted significantly on society. The application to economic theory of social and technological advances was pioneered by Marx in the nineteenth century   . Marx saw the development in industrial production as increasing capital and activity in the wider economy as well as fostering social change  . The evolution of economic theory in the twentieth century aligned the efficiencies of production to technological advances, industrial and economic growth  . The twentieth century saw the term innovation used by some writers to explain technological change  as well as being the subject of a body of literature assessing the processes behind the term. Early theories looked at the psychological aspects associated with innovation, the development of linear process models and the creative dimension of innovation was recognized  . Innovation was seen in the mid twentieth century as an instrument of economic growth  and economic survival for organizations”      . By the late twentieth century the term innovation had become entangled with advancement, technological change, social change and development across many strands of knowledge, across society and personalized to the individual  . In the twenty first century the term innovation signifies a myriad of meanings and concepts influenced by different factors over the centuries and some of these definitions are looked at in the next section.
3. Innovation: Definition
There are a significant number of definitions of innovation that are used across different fields in academia, industry, government and service provision. The academic literature available relates to a wide spectrum of disciplines and can cut across discipline areas   . For this study, it is important to have a definition of innovation that is suitable for the subject and research being undertaken. To do this, different definitions of innovation in the literature has been examined to establish an understanding of the components that make up the concept of innovation and specifically in relation to social housing.
The wide variety of literature and language used about innovation adds to different interpretations and understandings about basic concepts about the meaning of innovation   . As well as looking at the different components that make up innovation the literature also provides several models, theories and frameworks to understand innovation. Approaches have been made to establish a unified understanding of innovation  which would have some advantages around clarity and single purpose, but it has also been argued that such an approach would not be helpful  . The definition of innovation used in this study has been developed following a review of the literature and examination of the components of innovation. It supports the academic research being undertaken through this study to make a meaningful contribution to knowledge.
To start the examination of literature on innovation a selection of the key parts of several definitions from relevant literature are provided below in (Table 1). A note is placed next to each definition to justify its inclusion in the table.
Table 1. A sample of different definitions of Innovation in the existing literature.
Source: 1  , 2  , 3  , 4  , 5  , 6  , 7  , 8  , 9  , 10  , 11  .
These definitions contribute to the scope of the literature review, understanding of innovation and development of the definition that is used in this research study.
Table 1 shows different definitions of innovation and identifies some core components that make up innovation. It also shows some convergence of ideas and thinking regarding innovation  . These core components are taken and put into a composite definition of innovation as “the creative process whereby new or improved ideas are successfully developed and applied to produce outcomes that are practical and of value”  . A key component of the composite definition of innovation is the identification of the creative process which is discussed in the next section.
4. Innovation: The Creative Process
The creative process links creativity and innovation with the purpose of producing something of value that can be traded, developed and commercially exploited. Cropley et al.  say that they prefer the use of the term “value innovation” to more accurately describe the linked process involving creativity and innovation as it is more explicit and reflective of that operative environment. They see the linked process between creativity and innovation as one whereby a duality of approach is employed. Klein and Tremblay discuss creation and innovation within the context of urban, social and cultural development linking them as a linear process whereby “creation precedes innovation: and, innovation depends on the social acceptance of creation and the spread of its effects and results”  . Within this context the commercial impetus is less of a driving force behind the processes of creation and innovation. These processes and their connection can be viewed in different way and not just in the linear form  . A linear interpretation of the relationship between creativity and innovation excludes a range of other ways through which creative activity and innovation can take place as well as imposing a structured view of how creativity and innovation takes place and interrelates. This includes ideas that come into existence randomly or accidentally as well processes that can be unstructured, random and uncontrolled.
It has been suggested by some writers, that only certain people or groupings within society are creative  but it has also been claimed that everyone has the capacity to be creative  . If it is accepted that everyone has the capacity to be creative and that the processes involved are context dependent, then the unrestrictive nature of these factors would suggest that creative activity and innovation can take place through an infinite number of ways curtailed only by the restrictive factors that are also individual and context dependent.
Many different models of the creative process have been developed by researchers, academics, practitioners and others, however, not all writers agree that the creative process can be shown through a model. Vinacke  said that creativity within the artistic process does not follow a model and Wertheimer  saw the process of creative thinking as an integrated one. Within these different models there are some consistent themes including combining the development of ideas together with the use of imagination and analysis. The older models tend to look at the start of the creative process as being uncontrolled and linked to the subconscious processes within a person’s brain whereas the newer models tend to lean towards it being a controlled generative process.
5. Creativity: Academic Models
A study of creativity undertaken by Plsek  has highlighted several models within the literature on creativity that are important in explaining how the creative process has been analyzed by researchers, academics and practitioners. These creativity models can be criticized for being no more than frameworks for enabling thought and reason to be developed. Fritz  was dismissive of several writers who have developed models of creativity, in terms of their understanding of the subject itself, “many of these people have never created anything other than theories about creativity” (p. 4). Jung  identified two creative processes at work, the rational and the subconscious. The former is a conscious process involving the systematic processing and adapting of existing knowledge, the latter is a process internalized within the individual’s subconscious. Most models of the creative process seek to balance both these strands whereas a small number focus on one of the strands such as Barron  through his “psychic creation” model, this identifies creativity as being a mysterious process based upon the psychological and subconscious through four steps. Weisberg  identified from his work looking at the lives of great creators that moments of inspiration had been backed up by years of conscious work and preparation. The generation of an idea backed up by conscious preparatory analytical work also requires implementation to become fully realized. Contemporary researchers, academics and writers have developed models that embrace the complex aspects of the creative processes as it encompasses different developmental, contextual and applicability factors. In balancing creative and analytical thinking, models of the creative process have developed during the 20th century focusing on the harnessing of creativity to enable problem solving solutions to be developed. The development and implementation of creative solutions requiring the input of individuals, the right environment to be in place as well as the combination of elements highlighted through models of the creative process.
The creative process was presented by Wallas  in a five stage model in 1926 which was not only one of the first to be developed but has also been used as a basis for the development of subsequent models  . Wallas  believed that creativity was a legacy of the evolutionary process which allowed humans to adapt to rapidly changing environments and through his five-stage model he sought to explain insights and illuminations within the creative process.
The model presented in (Table 2) is treated in some academic texts as only having four stages with the “intimation” phase shown as a sub stage. The first stage preparation, is where conscious preparatory work on an identified problem or issue takes place including understanding it fully as well as attempts at resolution. During the incubation stage the issue or problem becomes internalized by the individual into their subconscious to be processed prior to the development of their insight, illumination or creative idea. A period taken during the “incubation” stage may help the individual to be more creative and aid their problem-solving

abilities as well as enabling misleading approaches to be forgotten. Leading on from this, it can be argued that, if a period is not taken during the “incubation” stage the individual may become fixated on taking forward an inappropriate approach to solve a problem. At the illumination stage the problem or issue returns to the conscious and the individual has a new insight or idea regarding it. At the last stage in the model the idea or insight goes through a verification process to assess its appropriateness and its further development.
Torrance  sees the work of Wallasas forming a lot of the teaching on creative thinking and that it has influenced the development of other models of the creative process. Wallas  noted that during the creative process outlined in his model the individual can return to earlier stages. The first and last stages of his model are placing purposeful preparation and critical verification together suggesting that critical and analytical thinking complement each other rather than contrasting against each other. It can be said that those who think creatively study, analyze, verify and judge but they have trained themselves to perceive, notice things, expect change and avoid making premature judgements. The implied theory behind Wallas’ model is that creative thinking is a subconscious process, it cannot be directed and that both creative and analytical thinking are complementary.
Building on the work of Wallas, Rossman  looked at the creative processes employed by 710 inventors and used the results obtained through a survey to develop a seven stage model  . This model begins with stages to observe and analyze a “need or difficulty” which may be reflective of his survey respondents but not necessarily a requirement of the creative process. The implication is that a “need or difficulty” has to exist and be identified before the creative process can take place. Rossman  has also added a final stage to “experiment and test the best fitting solution”, which may also be reflective of the survey respondents. This model has connotations of a positivist empirically based approach to augmenting creativity through a controlled process as opposed to a process that is built around enhancing a creative spark that has ignited. An element of mystery is still attached to the creation of an idea in Rossman’s model although the process identifies ideas as emerging at stage six as a response to an assessed need.
Table 3 shows Rossman’s seven stage model which begins with stages that observe and identify a need prior to generating a creative idea, in contrast, Wallas  whose model begins with preparation and incubation stages which develops an environment to foster creativity. The development of a creative idea is shown in Wallas’s model as an illumination which is inspirational which differs from Rossman’s model where the creative idea is seen as emerging through an analytical process. Unlike Wallas, Rossman  does not consider the process- ing of new ideas or insights that appear at the illumination stage to be subject to the subconscious “the assumption that the subconscious is responsible for the final solution is, however, no answer to the problem. It merely amounts to giving a name to a thing which mystifies and puzzles us”  .

The balance between the imaginative/uncontrolled aspects of creativity and the processes to analyze as well as control them are shown in the development of different models that try and explain the creative process. This could be said to be a microcosm of the historical view that creativity is linked to flair. Imagination, genius, artistic venture and it is uncontrollable together with a more contemporary view that has sought to harness, engage, understand, control and to use the energies of creative thought in a positive way. Taking elements of Wallas’s work forward, Osborn  developed a seven-stage model (Table 4) for creative thinking that balances both analysis and imagination.
As in the Wallas model, Osborn  includes the incubation stage, but his model shares a number of similarities with Rossman’s seven stage model. These include an assessment of a need, the gathering of data relating to this need, the assembly and selection of a solution as well as experimentation relating to the selected solution. Like Wallas  , Osborn  links creativity to the subconscious whereas Rossman  links it to a more rational and analytical approach. Wallas saw the creative process as an ongoing one whereby a “single achievement or thought” as “the making of a new generalization or invention” which can be dissected into a “continuous process, with a beginning, and a middle and an end”  . The stages within these models of the creative process can be seen as not being stages at all but processes occurring during creation which blend together. To be successful the creative process is described as “flow” by Csikzentmihalyi  whereby it is the result of the coming together of elements within a system; culture, an individual bringing novelty forward and external people who verify the idea or insight. He sees the role of the creative individual as being a link in the chain of a longer creative process and he sees creativity as “the cultural equivalent of the process of genetic changes that result in biological evolution, where random variations take place in the chemistry of our chromosomes, below the threshold of consciousness”  .
Osborn postulated that creative ideas are trapped in the minds of individuals because of the fear that people have of rejection if they are put forward. Osborn     developed brainstorming as a technique to be used to improve
Table 4. Breakdown of the Osborn seven-step model.

the generation of ideas, especially in group meeting through harnessing the groups collective knowledge and interaction to develop ideas. This process encourages participants to contribute to idea generation through an open thinking approach with equal weight put on each submission. Osborn identified four basic rules to be applied when using the brainstorming process; criticism is ruled out, freewheeling is welcomed, quantity is wanted, and combination/improve- ment are sought  . Rossiter and Lillien  see the generation of “creative ideas” as “vital to business success” and highlight that the principles behind brainstorming have “evolved considerably” since Osborn put forward the process. From the body of literature that has developed since the early 1950’s, Rossiter and Lillien identify six principles that have emerged that should be used with the brainstorming process; there should be instructions for each planned session, a target should be set for the number of ideas to be generated, ideas should initiated by individuals, initiated ideas should be refined group interaction, individuals should select the final idea through a voting process and session times should be controlled to short periods (15 minutes for initial idea generation and 2 hours for refining/selection)  .
The combination of imagination and control has been a continuing aspect of the development of models of creativity seeking to systemize techniques to enable the directing and analysis of creativity. An example of this is the Parnes-Osborn Creative Problem Solving (CPS) model which has developed alongside the use of brainstorming technique since the 1960’s  . Osborn introduced CPS with 3 steps-fact finding, idea finding and solution finding and this was refined by Parnes  into a five step model and again by Isaksen & Treffinger  who added a sixth step. In the model the first two steps (objective and fact finding) and last two steps (solution and acceptance finding) require the use of analytical thinking and the middle two steps (problem and idea finding) require the use of creative thinking.
Table 5 shows the Parnes-Osborn CPS model which builds on the Osborn seven stage model and Rossman’s stage model through a rational, analytical approach to harnessing creativity to solve an identified problem or achieve a goal
Table 5. Breakdown of the Parnes-Osborn CPS model.

 . The CPS model treats creativity as a tool that can be focused and used to generate solutions through an open, conscious and systemized approach whereas Wallas’s model looks at creativity as a process that illuminates ideas for potential solutions through the subconscious of an individual, which can be a random and closed process. When comparing the CPS model to Rossman’s model they both favor a rational and analytical approach to identifying the problem and implementation of the solution but differ in approach at the illumination stage where Rossman sees creativity as an unexplained process from which ideas emerge.
Koberg and Bagnall  put forward the “Universal Traveller Model” which has seven steps and again presents a balance between the imaginative and analytical aspects of creativity as well as a systematic approach to the development of the idea, generation of options, analysis and practical thinking. Step one of this model asks that that the user accepts the situation as it stands and to view this as a challenge unlike the other stage models where at step one the user is asked to; prepare for the problem or issue (Wallas), observe the problem or issue (Rossman), point to the problem or issue (Osborn) and find the problem or issue (Parnes-Osborn).
Koberg and Bagnall present their model (Table 6) as a map and the creative process as like taking a journey, starting with the problem and ending with a solution, using a process that they describe as “universally relevant” in that “any problem, dream or aspiration, no matter its size or degree of complexity, can benefit from the same logical and orderly “systematic” process employed to solve world level problems’  . They based their model on the study of Cybernetics, human control systems, employing the systematic approach used to develop a model that consciously controls creativity to design solutions to problems. They state that the creative “problem solving (design) process” is a “sequence of stages∙∙∙ on a journey to a destination” which once experienced and learnt is internalized by the individual  . The steps in their model “need not be linear”  which allows for the random nature of the creative process, this was also recognized by Wallas who stated, “it is unlikely that creative procedure can ever by strictly formulated”  . The seven steps in their model were also identified by Koberg and Bagnallas alternating between being divergent or convergent as well as having an evaluation step at the end of the process for review and planning.
Table 6. Breakdown of the Koberg & Bagnall “universal traveler” model.

This contrasts with the other stage models where the focus is on verification of the solution (Wallas), testing of the solution (Rossman), judging the solution (Osborn) and accepting/implementing the solution (Parnes-Osborn).
Models of creativity have also been developed to reflect certain contexts and specific environments such as engineering, commercial and business planning. These models still look to achieve a balance of creative and analytical thinking. An example of this is a model put forward for creative strategic planning by Bandrowski’s process for creative strategic planning. In this model (Table 7), Bandrowski places “judgment” in the middle as an important part of the analytical part of the process and he specifies the specific creative skills that are to be used to achieve the result through the process including skills in insight development, creative leaps, and creative contingency planning  .
Other models also look at providing a greater proportion to the external reality that an individual is applying their creativity to as well as the internal processes that they are employing, an example of this is the model put forward by Fritz as the “process for creation”  . He identifies the beginning of the process as the creative acts of conception and vision followed by analysis of current reality, action, evaluation, public scrutiny (building momentum), and completion as well as seeing the creative process is cyclical in nature-“living with your creation” being a meaningful end part of the process that leads to the next creative conception and vision.
Fritz’s model, which is shown in Table 8 focuses on the creative aspects of the individual and was sceptical of formulaic approaches to the classification of the creative process presented by other models. The stages identified in the models of Wallas, Rossman and Osborn focused on the identification of the problem and the application of a creative solution in contrast to Fritz whose focus is on the individual and the identification of problems and creative problem solving through their actions. The actions of individuals are fundamental to the identification of a problem as well as its solution and the level of motivation that an individual has affects these actions. A range of factors can impact on motivation including autonomy, ownership, influence, reward, challenge as well as personal

behaviour characteristics. In the literature relating to the motivation of staff working in organizations’ these factors can be identified; being in control, having independence, owning and influencing your own work    ; requirements to perform, achieve targets and timescales    .
6. Innovation: Social Housing
A significant amount of the literature identifies looks at innovation within social housing relating to the design and build of housing, reduced carbon usage and sustainable construction  -  . Innovation in technological advances in medicine and health care which is applied to housing services, mostly used by elderly people through telecare and assistive technologies  -  . There is very limited literature relating to innovation across the whole services provided by Housing Associations as social housing providers. Two studies that looked at innovation in HAs were undertaken by Walker & Jeanas  and a further study undertaken by Walker et al.  . Both used a two-dimensional typology put forward by Osborn  to look at innovations within their research studies.
This model built on the traditional split of innovation between product and process allowing for “innovation to occur at any stage of the life cycle thereby highlighting discontinuity (innovation) and continuity (organizational development) along the dimensions of services and users”  . Within the two-dimensional model, the first dimension focuses on the impact of organizational change upon the services that are delivered, and these are identified as existing or new ones which also includes the discontinuity of services. The second dimension focuses on the relationship of an organizational change to its users both new and existing as well as how their needs are met “which involves end-user discontinuity”  .
Four types of innovation were identified: the first is total innovation which includes “discontinuous change that is new to the organization and serves a new user group”, the second is expansionary innovation whereby “the change involves offering an existing service of the organization to a new user group”, the third is evolutionary innovation whereby “the change involves providing a new service to the existing user group of an organization” and the final classification is developmental innovation where “the services of an organization to its existing user group are modified or improved”  .

In the first study, Walker and Jeanas  researched innovation in three housing associations in the late 1990s. The organizations’ selected for the case studies represented the larger HAs in England who provided the most rented accommodation. A main problem identified with the case study approach was that it was not possible to gain a representative sample of housing providers as the sector is so diverse with no two organizations’ being the same  . The identified innovations were focused under six areas of activity: cultural change; customer focus/information technology; diversification; new management techniques; organizational expansion and organizational structure. Many of these were internally focused emphasizing service changes and reflecting the financial, commercial, customer service and performance within an operating environment that was constantly changing and becoming increasingly competitive.
From the study (Table 10), the researchers found that in relation to new innovations change is discontinuous and radical, though more limited, incremental innovation takes place through change. It was found that the iterative and dynamic nature of innovation make the process of classifying them problematic not only because this process can be subjective but also because the innovations themselves change through time. A further study  carried out on innovation in housing associations also measured innovations that had been identified against Osborn’s two-dimensional typology. Both studies highlighted several common themes that emerged from the transformation of the sector during the 1990s including: diversification of activity into regeneration, community facilities, care, special needs, private renting and contract management; the adoption of new organizational forms through mergers and group structures; a greater emphasis on a business ethos and management; and, a changing regulatory regime    .
This study shows that there is a process connected with innovation and that there are different definitions within the academic literature about innovation. Innovation can be considered as being product or process that is new or is existing

but has been improved. There are different models regarding the process of innovation and from these it can be identified that there is a strong link to creativity as part of the innovation process. In looking at the application of innovation in social housing as part of the public sector this study has focused on two academic studies which looked at Housing Associations and Innovation and these identified that innovations can be seen with a typology as new products or services or improvements on existing products and services. Further research could be undertaken to look at innovation within the social housing sector within the United Kingdom within the twenty first century.
