Project management literature talks about the need to measure and control all three variables of the project – Time, Quality, and Costs (or budget). Most project managers would tell from their experience that these variables have inherent conflicts. In many situations, when people try and speed up projects, they invest in additional resources, making the budget go haywire. While in many other situations, scope or quality is compromised to get a delayed project back on track. The conflict is also the other way round; when managers try and control budgets, time takes a backseat. (Long rounds of negotiation with multiple vendors cause significant delays in purchase items). Similarly, people try to scope more in a particular project to meet the ‘real’ needs of the client, thus compromising on time and budget. (for example, specific unplanned features that will help the client use the software more effectively!!). With this experience, the need to monitor and control these three variables evolved – so that there is no compromise on either of them. Good project management is to ensure that all the three variables meet the standards defined in the original commitment. This would entail that all three factors must be monitored and controlled. Right? This is a widely accepted theory. But in the real-time scenario, no effective solution has been developed to deal with the associated conflicts. It becomes very complex for a manager to derive the optimum from all three variables. For example, how much more time can one afford to spend on negotiating a cheaper deal with the vendor without compromising on project delivery. The extra time spent in negotiation may be recovered later, or it might not be. One can only check the efficacy of the decision in hindsight. In taking decisions at runtime, some managers choose between what is visibly getting compromised at that point in time or wherever there is maximum pressure for control. As a result many mangers find themselves focusing too much on one variable during one phase of the project and then focusing on the other in the next phase. For example, in many E&C projects, costs are very strictly controlled during the initial part of the project while time slips away and towards the end of the project, people spend a lot of time getting the project back on track. Similarly, in a software environment, you can find many scope compromises close to an important release date. In a shutdown project, many scoped items will be skipped at the end, when it becomes obvious that the due date is in jeopardy. Thus, we can conclude that attempting to manage all three variables together does not help. It adds to the complexity and encourages compromises all throughout the project. In the end, none of the variables are satisfactorily managed; people invariably look at compromises made on some of the variables and then conclude that they have to focus on all the three. Well focus on many, actually means no focus. To find a better solution, we need more understanding of how the variables are related. Many would claim that they all are negatively co-related. To be good with one means to be bad with the other. It is almost like trying to keep all the ping-pong balls simultaneously underwater in a swimming pool. You get one down, the other moves up. Right? However, in the actual execution of a project, time is the most important variable that controls the other two positively – to manage time effectively means to be good on costs and quality. It is only when the project goes out of control that the variables start becoming negatively co-related. Let us check with our collective experience.Most project environments suffer from significant waste in time, particularly in the initial part of the project. The projects gain momentum only close to important milestones or at the end when the resources stretch beyond their natural limits. The proposal finalization for new products may take months together but when it comes to final testing of the product, people expect it to be over as of yesterday. Similarly, it would take months to finalise a contractor, but resources will work 24 hours at the end to hit the delivery date. Managers would tolerate days of delays in customer approval of design in the initial part of the project but work overtime to meet the due date at the end of the project. Often people take up tasks without complete preparation in order to gain lost time thus leading to more rework and poor quality. If we are able to minimize this waste of time in the initial part of the project, then the pressure on time observed towards the end will reduce significantly. Most of the compromises made on budgets, scope, and quality actually stem from this pressure to complete the project in time. Projects which utilize time efficiently will also ensure a better quality output. So it is not surprising that projects which are delivered ahead of time are also delivered within budgets and with good quality. Even though hard data of project performance points to this relationship between quality and time, the commonly held belief is lesser time means poor quality. How have people developed the idea that time and quality are negatively correlated? It comes from their experience – they do remember that whenever there was pressure of time, quality and scope were compromised; hence, it is an obvious assumption that adequate time (read no time pressure) leads to better quality. It is true that when someone tries to do a task less than its touch time or the net time quality is bound to suffer but the key question is why did we end in this mess?  Retrospecting on the project, we invariably find a lot of time is wasted in the form of interruptions in the project or unnecessary work expansion in the earlier part, which could have been easily avoided. If that time was not optimized and utilized to its full potential, this situation would not arise. So, in a way, lesser project lead time actually means lesser pressure. The key is in maximizing time utilisation. Time seems to be the most important variable. Focusing on time throughout the project not only helps prevent compromises but in most project environments, time is directly related to money made by the company. For example, for a shutdown project, early completion means early production. For a multi-project environment, lower lead times means that resources are free much earlier to do more projects. For a large plant erection, early commissioning is earlier than planned pay back period. CCPM processes of execution help in preventing such waste of time in projects. Without intermediate deadlines and focus on buffer management, the pressure for meeting task deadlines goes away. With a focus on flow management, the issues causing interruptions are resolved ASAP. The flow of the project improves significantly while reducing the chaotic expediting environment. Resources do not overstretch to complete projects earlier. This, in turn, helps in improving quality and prevents scope compromises. Do we have a proof? Our experience does support the hypothesis.In our experience of implementing CCPM in a software environment, not only reduced the lead time but the bugs reported in the software also dropped. In a shutdown environment, CCPM implementation helped reduce the ramp-up time to peak production besides helping finish the project much ahead of schedule.(Ramp-up time to peak production is an indicator of quality of shut down projects). For a panel tool and die cast dies manufacturer, the sample quality improved from 85% accurate to more than 90% accuracy.

Key Takeaways

In project management, the battle between time, quality, and budget rages on. Conventional wisdom says that the 3 parameters are negatively co-related. But that is conventional wisdom. In reality, the most important parameter is time. Manage time effectively, and the other 2 will be positive.
