His current professional interests which include data and text analytics, decision making, sensemaking, knowledge management and collaborative approaches to problem solving in large organisations.
Kailash is the co-author of the Heretic’s Guides series of books. The first one, Heretic’s Guide to Best Practices, deals with collaborative approaches to managing complex problems. It won an Axiom Business Book Award in 2012 and was nominated for the Foreword Book of the Year Award in 2013.

When it comes to solving complex problems, we often perform elaborate rituals in the guise of best practices that promise a world of order, certainty, and control. But reality paints a far different picture, which practitioners are often reluctant to discuss. A witty yet rigorous journey through the seedy underbelly of organisational problem solving, The Heretic's Guide to Best Practices pinpoints the reasons why best practices don't work as advertised and what can be done about it.

– The purpose of this practice note is to describe the use of the issuebased information system (IBIS) notation to map dialogues that occur in project meetings.
– A case study is used to illustrate how the technique works. A discussion highlighting the key features, benefits and limitations of the method is also presented along with a comparison of IBIS to other similar notations.
– IBIS is seen to help groups focus on the issues at hand, bypassing or avoiding personal agendas, personality clashes and politics.
– The technique can help improve the quality of communication in projects meetings. The case study highlights how the notation can assist project teams in developing a consensus on contentious issues in a structured yet flexible way.
– IBIS has not been widely used in project management. This note illustrates its value in helping diverse stakeholders get to a shared understanding of the issues being discussed and a shared commitment to achieving them.

We present experimental data demonstrating wall slip of high temperature polymer melts at high shear rates (up to ~70 s -1 ) without pressure and viscous heating effects. Results for polydisperse (linear low density polyethylene) and monodisperse (polystyrene) melts are presented. For the monodisperse case two distinct regimes of slip are seen: (1) a low shear rate regime in which the slip velocity increases slowly with shear rate (weak slip) and (2) a high shear rate regime in which the increase is dramatic (strong slip). Through scaling of our shear stress/shear rate data we demonstrate that the crossover between the two regimes occurs when the bulk polymer chains are effectively disentangled. These findings are in qualitative agreement with molecular models of slip which invoke an entanglement-disentanglement scenario for the transition from weak to strong slip. The polydisperse system shows less critical slip behaviour and the slip velocity increases; yet, the increase is less dramatic than the monodisperse system. (C) 2000 Elsevier Science B.V.

We present an approximate theoretical treatment of pressure and viscous heating effects on the flow of a power law fluid through a slit die. It is assumed that the flow remains one dimensional, and the accuracy of this approximation is checked via finite element simulations of the complete momentum and energy equations. For pressures typically achieved in the laboratory it is seen that the one dimensional approximation compares well with the simulations. The model therefore offers a method of including pressure and viscous heating effects in the analysis of experiments and is used to rationalize experimentally obtained pressure profiles for the flow of polymer melts through a slit die. Data for the flow of a linear low density polyethylene and a polystyrene melt in a slit die show these two effects are significant under normal laboratory conditions. Thus, the shear stress-shear rate curves will be affected to the point of being inaccurate at high shear rates. In addition, it is found that the typical technique to correct for a pressure dependent viscosity is also inaccurate being affected by the viscous heating and heat transfer from the melt to the die. © 1999 The Society of Rheology.

Mackay et al. (1995) have presented an approximate technique to determine the elongation viscostiy from pressure drop measurements in a simple stagnation flow device. In the present paper we describe experiments using a high viscosity Newtonian oil, aimed at probing some of the assumptions made by Mackay et al. We find that Trouton ratios calculated using the original analysis are well above the value of three expected for Newtonian fluids. Finite element simulations of the flow field show this is due to the net pressure drop having a substantial shear contribution which should be corrected for before the Trouton ratios are evaluated. Interestingly, most of the shear correction is due to shear on the inside of the orifice near the exit from the central flow region. The shear contribution to the pressure drop occurs for all flow rates, however, at large flow rates there is also an inertial correction to the pressure drop. In this paper we describe an approxiamte method that corrects for both shear and inertial effects. With these effects recognised and corrected for, the measured Trouton ratios are reduced to around three.
An obstacle in the path of a water jet emerging from a tap gives rise to a stationary wave pattern upstream of the obstacle. In this paper, the wavelengths and the damping coefficients of these waves are calculated for various jet radii and velocities. The calculations indicate that the wavelength decreases and the damping coefficient increases with increasing jet velocity, in qualitative agreement with observations. ©1996 American Association of Physics Teachers.

An obstacle in the path of a cylindrical fluid jet creates axisymmetric stationary capillary waves upstream of the obstacle. These waves can be easily observed on low velocity water jets issuing from taps. The presence of a surfactant on the jet surface will give rise to surfactant induced stationary modes. In this note we derive the dispersion relation for surface waves on a cylindrical fluid jet with an insoluble monolayer of surfactant on its surface, with a view to investigating surfactant induced stationary modes. The dispersion is seen to have infinite wavelength stationary solutions corresponding to an exponential decrease of excess surfactant concentration. The decay coefficient of these modes increases with increasing jet velocity and decreases with increasing surfactant concentration. This phenomenon offers a novel method for determining the interfacial properties of a freshly formed surface.
The effect of a particular type of thermal fluctuation in a DNA molecule is to reduce the hydrogen-bond force constants locally. In this paper we study the effect of such thermal fluctuations on the vibrational spectra of B-form poly(dG)poly(dC) and B-form poly(dA)poly(dT). We find the fluctuations create a defect (decrease in H-bond force constants) that is localized to a single base pair. In both polymers the presence of such a defect induces prominent defect modes in the frequency region between 60 and 72 cm-1. The mode found in poly(dG)poly(dC) is quasilocal (inband), whereas the mode found in poly(dA)poly(dT) is local (lies in the band gap). Our calculations indicate that it is easier to create the defect mode in poly(dA)poly(dT) than in poly(dG)poly(dC). The local mode in poly(dA)poly(dT) is at a frequency where infrared absorption occurs. © 1989 The American Physical Society.
The reduction of the interbase hydrogen-bond force constants in a unit cell of B form poly(dA)-poly(dT) creates a local mode in the gap between 63.9 and 66.7 cm-1. This mode emerges from the band with a zone-center frequency of 66.7 cm-1. This band has a large h-bond stretch amplitude. Our calculations suggest that this local mode can be created by thermal fluctuations in the perfect homopolymer. We track the behavior of this mode with softening of the h bonds. As expected, we find that the mode shifts to lower frequencies as the bonds soften. The h-bond stretch amplitudes are found to increase with h-bond softening, up to a point, beyond which they decrease with further softening. © 1989 The American Physical Society.
