The research evaluated and compared the effectiveness of the choice between ALAP and ASAP constraints in construction scheduling using the MS project software. A problem is identified that users of the MS project are not well guided in the choice of start date constraints applied in scheduling project tasks. It showed from literature that most practitioners who use this software apply only as soon as possible constraint option which may not produce the best project outcome in every project scenario. Using 'whatif'questioning technique in a quasi-experiment research design two hypotheses are developed and tested using ANOVA to evaluate and compare the effectiveness of choice between ALAP and ASAP constraints applied to schedule tasks in developing the construction schedules. The Null of hypothesis 1 states that: There is no significant relationship between the start date constraint and activity start variance. And the Null of hypothesis 2 states that: There is no significant relationship between the start date constraint and activity finish variance. Activity start variances were measured in a quasi-experiment for different scheduling options of ALAP and ASAP constraints and their differences tested using ANOVA if observed differences were due to mere chance or that they are due to different constraint types of ALAP and ASAP applied. Results show that F CAL = 81.

The report identified the research problem that users of the MS Project are not well guided in the choice of start date constraints applied in scheduling project tasks. It showed from literature that most practitioners apply only as soon as possible options which may not produce the best project outcome in every project scenario. Two hypotheses were developed and tested using ANOVA. The Null of hypothesis 1 states that: There is no significant relationship between start time constraint option and activity start variance. And the Null of hypothesis 2 states that: There is no significant relationship between the start time constraint options and activity finish variance. Activity start variances were measured for different scheduling options and their differences tested using ANOVA if observed differences were due to different scheduling options of ALAP and ASAP constraints applied. Results show that FCAL = 81.15 and FTAB = 98.50 at 1% level of significance and FTAB = 18.50 at 5 % level of significance. Since FCAL < FTAB at 1 % level of significance, we accept H1: That there is a significant relationship between start time constraint options and activity start variance at 1 % level of significance. The probability of project completion (PR) was estimated as: PI=100 –51=49%; PII=100 – 47=53%; PIII = 100 – 45 = 55%. Where PI, PII and PIII are the schedules developed using different constraint options. This data reduction of the case study project shows very clearly that the probability of project completion on the due date, PR improves with introduction of ALAP constraints in some selected activities. This results emphasis the importance of scheduling to reduce activity start time variance by selectively scheduling some identified tasks to occur as late as possible. The reported study provides concise evidence of the scenarios and right application of the ALAP and ASAP constraints in the Microsoft Project Planner and the Primavera Project Planner pieces of software.

This paper reports the methodology adopted in developing a generic procedural framework for evaluating the effectiveness of construction project schedules.A problem is identified from literature that users of the MS Project are not adequately guided in making choice of start date applied in scheduling the project activities. Most users applies as soon as possible while a few apply as late as possible schedules. But the extent to which this is a practical and effective scheduling option is in question. Two hypotheses were formulated and tested using ANOVA in a pilot survey to assess whether or not a problem exist as defined and if solution can be sought in the way and manner conceived.Null of hypothesis 1: There is no significant relationship between start time constraint option and activity start variance. Null hypothesis 2: There is no significant relationship between the start time constraint option and activity finish variance. Results show that F cal= 0.86, F tab = 5.14 at 1 % level of significance and F tab = 10.9 at 5 % level of significance. Since F cal < F tab we accept H1: That there is a significant relationship between start time and activity start variance. This suggests that schedules based on as late as possible experience reduced activity start variability that events are likely to occur as planned. This is desirable.

It defines and explains the ALAP and ASAP constraints. It covers both MS Project and Primavera Project Planner pieces of scheduling software which have such constraint features: As Soon As Possible (ASAP); As Late As Possible (ALAP); Start No Earlier Than (SNET); Start No Later Than (SNLT); Finish No Earlier Than (FNET); Finish No Later Than (FNLT); Must Start On (MSO); and Must Finish On (MFO). Several literature sources show that only few practitioners know how to apply these constraints properly. They contend that scheduling practice is done on a hit or miss basis without regards to best practice standards. This book is an attempt to replace intuition with scientific reasoning. Practitioners do not know what project scenarios should early or late start scheduling option are applied. The book prepares users of scheduling software to develop project schedules that are effective with reduced possibility of...

The research identified a problem that users of the Microsoft Project are not well guided in choice of start date constraints applied in scheduling project tasks. Most practitioners apply only as soon as possible constraint option which may not produce the best project outcome in every project scenario. Using ‘what-if’questioning technique in a quasi-experiment research design two hypotheses were developed and tested using ANOVA to evaluate and compare the effectiveness of choice between ALAP and ASAP constraints applied to schedule tasks in developing the construction schedules in different project scenarios. Two hypotheses are developed and tested using ANOVA if the observed differences were due to mere chance or that they are due to different constraint types of ALAP and ASAP applied. Results show that FCAL = 81.05 and FTAB = 30.80 at 1% level of significance and FTAB = 9.55 at 5 % level of significance. Since FCAL is significantly large and FCAL > FTAB at both 1 % and 5 % levels of significance, we reject H0 and accept H1: That there is indeed a significant relationship between start date constraint and activity start variance at both 1 % and 5 % levels of significance. The paper concludes that the scheduling software developers can apply new features to assist users make correctly choice of as soon as possible constraint or as late as possible constraint.
