Abstract. Usability has been used to design and assess products and websites. This paper takes the concept of usability one step further and proposes a framework to assess suggestion systems. Thus taking the concept of usability one step further and applying it in the area of ideas management through suggestion system. The fundamental premise of the article is that a suggestion system designed, with usability in mind, will improve innovation among employees, and hence increase participation. This framework was then used to assess four suggestion systems in an oil and gas company in the middle-east. These systems were further assessed for employee perception of their usability and participation. After collecting data on these three different aspects conclusions are drawn. Out of the four systems analyzed, the most usable suggestion system had the highest participation rate and the least usable system attracted the fewest suggestions.

Purpose -The purpose of the paper is to investigate the critical success factors (CSFs) associated with the effectiveness of transfer and sharing of tacit knowledge in lean and agile construction processes.Design/Methodology/Approach -The study identifies ten critical success factors that initiate the transferring and sharing of tacit knowledge. The CSFs are validated through quantitative study. This study recruited project managers, executives, consultants, and other managers that are directly involved in the management of a construction project. It recruits the respondents those have background and experience from disciplines such as lean construction, agile construction, Construction Supply Chain (CSC) and KM in lean, agile and CSC. The data collected through selfadministrative questionnaire, is categorised as ordinal data, analyzed in SPSS with Frequency and Kruskal-Wallis H test and Spearman's correlation analysis. A rank order analysis is performed to establish the level of importance of those factors. Findings -Initially, 'Trust between construction organisations' is identified as the foremost CSF.Moreover, other CSFs such as, motivation, leadership capabilities, business strategies and organisational capabilities follow trust.Originality/Value -This is the first study that investigates and establishes the CSFs that are essential to initiate transferring and sharing tacit knowledge in a lean and in an agile construction processes.

Purpose -The purpose of this paper is to present the findings of a workshop organized in New Delhi to assess the current state of green construction in India and highlight the major drivers and challenges faced by the construction sector. Design/methodology/approach -The data collection for this paper is conducted through two sources; a survey and a facilitated brainstorming session. The survey provides an opportunity to compare practices in India to global trends and the facilitated sessions provides a platform to collect data on more subjective, experiential knowledge about green construction in India. Findings -Some of the major findings of this endeavour are: there is an awareness about green construction in India; It is primarily driven by the governmental and international regulations; with the current energy crisis customers in India are actually willing to pay extra for going green; and there is a lack of accurate lifecycle cost assessment models which results in misconceptions about associated costs of going green. Originality/value -This paper has provided a brief overview of green construction in India. It has also provided a list of major challenges and drivers for implementation of green. This list of challenges and drivers can provide practitioners, regulators, and academics knowledge about means to focus their future efforts in implementation of green.

Purpose -This paper investigates the potential challenges that hinder the effective transfer and sharing of Tacit Knowledge (Knowledge Communication) within a construction supply chain (CSC).Design/Methodology/Approach -This study identifies six challenges (through literature review) with fifteen positive correlations between them. Quantitative methodology is employed to validate those challenges and correlations between challenges. Firstly, data is collected through semi-structured e-survey questionnaire. Afterwards, a Frequency and Kruskal-Wallis H test is run for initial validation of identified challenges. A correlation analysis is used to highlight the taxonomic relations between those challenges. Finally, the study establishes the rank order of the first and following challenges.Findings -This study highlights that traditional ways of working with construction organisations are the predominant challenge that hinders effective transferring and sharing of Tacit Knowledge. The cause of challenges is the fragmented nature of CSC. Also, it brings out the correlation between those challenges. The study draws the conclusion and recommendation to implement Knowledge Communication (KC) within a CSC.Originality/Value -The study highlights the challenges that hinder KC in a construction process of a CSC. It establishes that the fragmented nature of the construction sector is not the first challenge that hinders implementation of transferring and sharing of Tacit Knowledge but somewhat traditional organisation structures and working processes. This is the first paper that investigates and tests the challenges in four dimensions and establishes the rank order of challenges with crucial distinction in a KC approach within a CSC.Conclusion -This study identifies the rank order of challenges. It also discusses the implementation of KC within a CSC. It reflects the current understanding of KC in the construction sector and pinpoints the contribution of this study in academia and practice.

Purpose- This study develops a success factor model to understand and facilitate improved cost\ud management system (CMS) implementation in Low-cost housing (LcH) project delivery in Nigeria.\ud Design/methodology/approach- Literature findings highlight thirteen drivers’ affecting effective\ud implementation within the CMS and employs series of brainstorming sessions and questionnaire\ud survey to validate the drivers’. Factor analysis (FA) identifies possible contextual relationships\ud among the validated drivers’ and groups them into three success factors. The results of the FA are\ud refined employing interpretive structural modelling (ISM). The ISM identifies and models the\ud influential drivers’ and aids the development of the success factor model.\ud Findings- Effective team qualities, information and management actions and a stable operational\ud environment are the three essential success factors for effective CMS implementation.\ud Practical implications- The paper highlights effective team qualities as the most important CMS\ud considerations for Nigerian LcH project delivery. This finding creates the needed awareness to\ud guide project sponsors and project managers in the appropriate selection of Project Management\ud Team (PMT) as well procurement system that facilitates their collaboration.\ud Originality/value- This study is a novel research using FA and ISM to investigate the influence of\ud success factors needful for effective implementation within the CMS. It further develops a hierarchy\ud model that aids the PMT with the better understanding of the drivers’ and factors interrelationships\ud for use on LcH projects within the Nigerian context
