Abstract
Purpose
The purpose of this paper is to identify control systems that give rise to better construction project performance; and develop and test project performance predictive models based on control systems adopted in the project.
Design/methodology/approach
Research design was questionnaire survey. Data were collected via Electronic mails. The sampling frame was Singapore-based construction firms.
Findings
In all, 16 control mechanisms are significantly correlated with project outcomes. The more important control mechanisms are: adequacy of project information to develop the project schedule; adequacy of float in the schedule; and quality of techniques used to support risk identification. Two relatively robust predictive models were constructed and validated to predict schedule and quality outcomes of construction projects. Schedule performance may be predicted by adequacy of float and stringency of criteria to select suppliers. Quality outcome is most significantly affected by competency of quality manager, rather than the hard systems adopted in the project.
Research limitations/implications
The limitations include low response rate, and subjective nature of the five-point Likert scale used to rate project outcomes and extent to which control mechanisms were adopted in the project.
Practical implications
The implication of the findings is that merely having good project management practices and adequate resources are not sufficient to achieve good project outcomes. Instead, construction projects need to have control systems in place, as they play an important role in project outcomes.
Originality/value
The paper has shown empirically that control systems affect project outcomes. They are needed not just to control the project, but also help the project to achieve good outcomes. The research designed and tested two relatively robust models to predict schedule and quality outcomes of a project. These models may be used to make an initial assessment of the project's likely outcome, based on the control systems that contractors are going to adopt.

Abstract
Purpose
This paper aims to highlight recent resources on information literacy (IL) and library instruction, providing an introductory overview and a selected annotated bibliography of publications covering all library types.
Design/methodology/approach
This paper introduces and annotates English-language periodical articles, monographs, dissertations and other materials on library instruction and IL published in 2015.
Findings
This paper provides information about each source, describes the characteristics of current scholarship and highlights sources that contain either unique or significant scholarly contributions.
Originality/value
The information may be used by librarians and interested parties as a quick reference to literature on library instruction and IL.
