Velocity Accelerators®: Critical Chain Project Management

Posted September 1, 2018 By Fletcher Groves

One of the areas we single-out for deeper discussion in a Pipeline workshop™ – what we call Velocity Accelerators® – deals with the imperative of replacing the current method of scheduling houses under construction.  Not a house.  Not every house, independently.

No – this is about the method of scheduling the entire set of houses a builder has under construction.

That is because the nature of the workflow in homebuilding production is project portfolio management.  Yes, there is workflow performed in processes, but those processes are generally embedded, enabling, and supporting;  process workflow is different than project workflow.  The process of building a home – what we call the Start-to-Completion process – is actually the management of multiple projects that share resources.  It is the structuring and the management of a portfolio of job schedules, with interdependencies and interactions of tasks and resources.

Homebuilding is multi-project management.

The current method of project scheduling is known as the Critical Path Method (CPM), which evolved from the Program Evaluation and Review Technique (PERT) in the 1950s;  it has been in existence for more than sixty years;  it is the method used in every homebuilding ERP.

PERT and CPM were designed for programs with large, complex structures (Polaris weapons system, the Manhattan Project), but the Critical Path Method has become the de facto standard for scheduling all types of projects:  aerospace/defense, software development, product development, research, and – yes – construction.

The problem with CPM is that it was not designed for managing a portfolio of projects, and it was not designed to function in environments where velocity is important, where faster cycle time and higher inventory turns are critical drivers of business outcomes.

Where it must contend with variation and uncertainty, CPM offers only a buffer of additional time – individual task durations lengthened to protect the completion date of each task, but not necessarily the completion date of the project.

For the most part, builders are oblivious to the effects of variation on their production system.  The cost of variation is always the same:  it is the Gross Income lost from all of the closings that never occurred, from houses that were never built with the capacity they paid to have;  for a profitable builder, it is Gross Income that would have become Net Income, and ultimately, Net Profit.

It’s a lot of money.

Moreover, CPM considers task dependency (the predecessor-successor relationships of tasks) in its work breakdown structure, but it does not resolve resource contention;  it does not consider situations in which tasks of different projects/jobs depend on the availability of resources that do not have sufficient capacity to meet the demand being placed upon them.

These two factors – dealing with variation and resolving resource conflict – should be anathema to builders.

CPM was not designed to contend with the production environment homebuilding presents.  It is not the problem (the problem is variation and resource conflict), but CPM is benign to the solution.  ProChain Solutions’ Rob Newbold (Project Management in the Fast Lane) told me that he would go further, saying:  “CPM supports values that perpetuate the problems of homebuilders.”

Which brings us to Critical Chain Project Management.

Developed in 1997, Critical Chain addresses task dependency and resource contention, and it replaces padded durations intended to protect task completion dates with buffers that protect the completion date of the project/job;  CCPM is much more aware of system constraints.  Most importantly, Critical Chain substantially reduces the duration of projects – the cycle time of houses under construction.

Consider the explanation of an exercise excerpted from the RB Builders: Lessons from the Pipeline© business case study being used in the upcoming Pipeline Workshop™ No. 10:

“RB Builders’ newly-acquired division has a construction schedule of 150 calendar days, but its actual cycle time is 225 calendar days.  There is wide agreement that it should be able to build its homes in far-less than 150 days, because the schedule reflects ‘highly certain’ task durations.  Switching from CPM to CCPM would immediately reduce the schedule from 150 days to 121 days, cutting the schedule by almost 20% with no diminution of confidence;  it would reduce the actual 225 day cycle time by almost half (46%).”

Critical Chain Project Management does more than just reduce the length of construction schedules.  It also specifies a set of rules preventing behaviors that consume (and waste) the safety CPM builds into task durations.  It installs a release mechanism that “pulls” starts into the system and keeps work-in-process at the levels required to produce faster cycle times.

It implements simple, visual tools to manage production.

Builders can put a number of these practices into place without changing the scheduling algorithms from Critical Path to Critical Chain.  They can implement standalone CCPM software applications.  However – Critical Chain will not be a complete, integrated solution for the homebuilding industry until its management technology providers wake up and address it.

It all starts with obtaining the knowledge necessary to insist on that change.

At every Pipeline workshop™ we have ever done, one of the most important takeaways, one articulated by virtually every homebuilding company executive in attendance, is simply this:  something has to be done with the notoriously fragmented value stream that defines their industry, if they are going to have any hope of managing production as a system.

In their landmark 1996 book, Lean Thinking, Jim Womack and Dan Jones defined a value stream as “the set of all the specific actions required to bring a specific product through the three critical management tasks of any business.”  They went on to describe a set of processes, which they termed tasks:  a problem-solving task, an information management task, and a physical transformation task.

By definition, a value stream does not belong to an industry;  it is enterprise-specific;  each value stream belongs to its enterprise;  thus, every homebuilding company has its own value stream;  it owns it.

Nevertheless, it would be a challenge to cite any other industry, in which the sequence of tasks in the most common versions of that industry’s core-critical process (start-to-completion, i.e., the physical transformation task) is performed entirely by separate entities, as is the case with homebuilding.

Look at the value stream of almost any homebuilding enterprise, and you will find a combination of independent, separately-owned, non-proprietary, non-exclusive, unaffiliated businesses, each having their own goals, more often than not at-odds with each other.

We have a descriptive phrase for that practice:  “strip-mining the value stream”.

Technology – specifically, offsite manufacturing processes – will improve quality, reduce waste and variation, reduce cycle times, increase productivity.  By all means, consider it.  But, by definition, manufacturing off-site doesn’t unify the value stream, unless you own or joint venture the facility.

In her final comments to the team at RB Builders, before she left them the first time (The Pipeline: A Picture of Homebuilding Production©, Second Edition), the intrepid, results-based consultant reviewed the components of RB Builders’ production management system – the RB-IPS – and said this:

“It is a production management system that specifies the means by which RB Builders fosters epic relationships of mutual interest with its building partners and supply partners.  The RB-IPS provides both the process and the program for progressively transforming subcontractors and suppliers into true partners, into trusted allies, joined by shared, mutual interests.”

Builders attending Pipeline workshops™ consistently emphasize the need for stronger trade-partnering, better coordination, more cohesiveness, a more unified approach to managing the trade side of production.

They acknowledge the obvious:  they do not have the internal resources necessary to perform “the set of all specific actions” required to bring houses through the start-to-completion process, and they are completely dependent and reliant on skilled construction resources that are in short supply;  they understand that they can no longer dictate the terms.

Is vertical integration part of the answer?  We have been suggesting, for almost 20 years, that builders at least consider that possibility, that they find a way to discontinue the strip-mining operation.  That suggestion usually falls on deaf ears, or is dismissed as a radical, undoable notion.

Which is where opportunity always lies, in radical, undoable notions.

Whether or not vertical integration has a future strategic role to play in the homebuilding industry remains to be seen.  Starting with this Pipeline workshop™, it is portrayed in one of the Pipeline games™;  it is an area that has been covered in the Lessons from the Pipeline© business case at previous workshops;  and it was added as a section in the second edition of The Pipeline: A Picture of Homebuilding Production©, which was released for publication in 2016.

The outcome of the vertical integration question doesn’t change the underlying imperative.  Success in unifying the effort of even the existing value stream has profound ramifications, on both the margin and velocity components of Return on Assets;  and success in unifying the value stream has profound implications for creating competitive separation.

With or without vertical integration, addressing the issue will require Epic Partnering™.

Velocity Accelerators®: Business Process Improvement

Posted August 18, 2018 By Fletcher Groves

An overwhelming portion of SAI Consulting’s work, in and out of homebuilding, has been about enabling clients to better structure themselves around their core-critical business processes;  Business Process Improvement is the area of our practice for which we are most recognized.

It is a similarly important area for Continuum Advisory Group, the consulting firm that joins SAI in the facilitation of open, sponsored Pipeline workshops™ and Pipeline seminars™.

There is a good reason for our firms’ collective focus on improving (and managing) business processes, and it is simply this:

The most basic, most fundamental premise in all of business is this:  the reason an enterprise exists – every business enterprise, certainly every homebuilding enterprise – is to make money;  the way an enterprise makes money is by delivering value to its customers and other stakeholders;  that value can only be delivered through the work that the enterprise performs;  that work has to be performed in some manner of workflow;  the most common form of that workflow is work performed in processes.

Make money . . . by delivering value . . . through the work you perform . . . in processes.

From a business standpoint, processes are critically, centrally important;  they exist – they matter – whether homebuilders are intentional about them or not.

How important is Business Process Improvement to a homebuilding company?  Important enough that, sometime ago, we sacrificed one of the highly-regarded Pipeline games™, so that we could elevate improvement of workflow to the level of a Velocity Accelerator®.

At SAI, we repeatedly make the point that Pipeline workshops™ are all about thriving on the velocity side of Return on Assets®, but better process workflow pays off on both sides of economic return;  it drives both higher margins and higher velocity, drives a higher Return on Sales as much as it drives higher Asset Turn.

Consider:

Start-to-Completion – the sub-process within Prospect-to-Closing that is the aorta of workflow in a homebuilding company – is not, at its core, process management;  it is multi-project management;  it is project portfolio management, with embedded and supporting processes;  it is workflow in which all of the non-supervisory work is performed by external resources (trades and suppliers).

Since it is not managed like a process, we don’t map it like it is a process.

Yet – yet – the results from the dozens of process mapping engagements SAI has performed that don’t consider Start-to-Completion, nonetheless show that fully 25% of all the work a homebuilding company does perform – the work that consumes a building company’s overhead – is completely non-value-adding.

Ponder that revelation for a moment.

Here is the bottom-line:

If your Operating Expense represents – meaning it consumes – just eight percent of Revenue, you are throwing away $20,000 of every $1,000,000 in Revenue you generate.

The most visible element of BPI (and BPM) is the mapping of process workflows;  however, process mapping involves far more than documenting – and confirming, accepting as-is – the current state of that workflow;  it includes redesigning those workflows in ways that improve them, which invariably reveals other issues – the root causes, the core problems – that affect profitability and economic return.

Which makes understanding and improving workflow the means to a much more important end.

Business Process Improvement is the tip of the spear, the front-end of a continuous improvement methodology in which the activities and elements of workflow that add value are preserved, the activities and elements that add no value are eliminated, and the remaining activities and elements that enable value are refined to make the workflow more clear, more consistent, more streamlined, more connected, more succinct, more fit for its intended, defined purpose.

The analogy from our Pipeline workshops™ is that we want a shorter, straighter pipe.

Because it is so foundational, it is impossible to overstate the importance of understanding and improving the way work is performed, before starting down the long road on other improvement initiatives, before the process of continuous improvement moves anywhere else.

In addition to being the means to a more important end – and the front-end of a process of continuous improvement – BPI ushers in a new perspective.

It shifts the organizational view away from the internal structure of work performed in functions. towards the value-producing flow of work performed in processes.  BPI shifts the perspective from vertical to horizontal;  it turns a homebuilding enterprise 90 degrees from vertical, lays the enterprise on its side, and aligns its workflow with the value it seeks to create.

It’s about getting horizontal.

Lastly, processes are also the centric element of the operating model that forms any strategic value discipline that serves to deliver exceptional levels of the specific and distinctive value demanded by a narrowly-defined segment of homebuyers.

Pipeline Workshops™: Velocity Accelerators®

Posted August 11, 2018 By Fletcher Groves

If you had to choose a single word to associate with a Pipeline Workshop™, it would be velocity – a vector measure that means speed in a purposeful direction.

We want to elevate velocity to an equal standing with margin, because, together, they are the components of economic return.  In each Pipeline workshop™, we select specific areas of production management for a deeper dive – more discussion, the use of pointed and challenging exercises from the RB Builders: Lessons for the Pipeline© business case, etc.

These areas are known as Velocity Accelerators®.

Velocity Accelerators® tend to be important areas that do not receive sufficient industry attention;  in fact, beyond a passing understanding, Velocity Accelerators® are often the first meaningful exposure to these areas builders attending a Pipeline workshop™ have experienced, making these sessions something of a mini-boot camp.

For the upcoming workshop (Pipeline Workshop™ No. 10, September 26-27, 2018, at the Ponte Vedra Inn and Club, in Ponte Vedra Beach, Florida), we are highlighting five areas:

Epic Partnering™.  Builders attending Pipeline workshops™ consistently emphasize the need for stronger trade-partnering, better coordination, more cohesiveness, a more unified approach to managing the trade side of production.

They acknowledge the obvious:  they do not have the internal resources necessary to perform “the set of all specific actions” required to bring houses through the start-to-completion process, and they are completely dependent and reliant on skilled construction resources that are in short supply;  they understand that they can no longer dictate the terms of engagement.

Developing the business relationships that unify a builder’s value stream is a program of milestones and features, and it is a transformative process;  it is both a program and a process.

Epic Partnering™ has profound implications on both the margin velocity sides of economic return.

 

Business Process Improvement (BPI).  The most basic, most fundamental proposition in the business of building homes is this:  the reason a builder exists is to make money;  the way a builder makes money is by delivering value – benefit in excess of cost – to its homebuyers and other stakeholders;  that value can only be delivered through the work that the building enterprise performs;  value-delivering work has to be performed in some manner of workflow, which includes work performed in processes.

Make money . . . by delivering extraordinary value . . . through the work a builder performs . . . in processes.

BPI is the front-end of a process of continuous improvement, one that fundamentally changes the perspective of workflow, and becomes the driving component of the operating model that forms a builder’s strategic value discipline.

As with Epic Partnering™, BPI improves both margin and velocity.

 

Critical Chain Project Management (CCPM).  Developed more than sixty years old, the scheduling algorithm known as the Critical Path Method (CPM) was never intended to function in the environment of homebuilding production, which is essentially project portfolio management with surrounding, supporting, and embedded processes.

CPM was never designed to function in environments in which velocity is important, where faster cycle time and higher inventory turns are critical drivers of business outcomes.  Moreover, CPM is oblivious to the devastating effect variation has on the scheduling of a production system.

CCPM is the leading edge – the future – of project scheduling for homebuilding;  it promises significant improvements in managing homebuilding production – faster cycle times, faster inventory turns;  enabling homebuilders to generate more Revenue, more Gross Income, with a planned, finite, and controlled amount of work-in-process and production capacity.

Unlike either Epic Partnering™ or Business Process Improvement,  Critical Chain is purely a velocity proposition.

 

Building Information Modeling (BIM).  Building Information Modeling (BIM) explores building design in a 3D model of the three spatial dimensions of width, height, and depth (some would also say time and cost), and links to multiple databases with information on costs, schedules, specifications, engineering data, and more.

BIM integrates, consolidates, and links information;  it makes data more accurate, useful, and manageable.

As with Epic Partnering™ and Business Process Improvement, BIM has implications for both the margin side and velocity side of Return on Assets:  on the margin side, better, more collaborative designs with fewer design errors, more accurate job cost books, job budgets, and purchase orders;  on the velocity side, plans that are easier to build, more dependable job schedules, shorter cycle times, faster inventory turns.

Plus – a more satisfying homebuying experience and a higher quality product.

Building Information Modeling holds the possibility of “making product 35% faster and 25% less costly to build”, according to Continuum AG’s Clark Ellis.

Yet, for all its promise to transform the homebuilding industry, BIM has had a shallow adoption curve, largely because implementing BIM requires a lot of money, too much determination and resolve, a different mental model, and a willingness to abandon past practices.

Which is where opportunity lives.

 

Open-Book Management and Team-Based Performance Compensation:  The efforts of a homebuilding company to improve operating performance and business outcomes will become far more difficult – it will likely fail – if it does not succeed first in creating a homebuilding team that works toward commonly-held and commonly understood business goals, versus being a collection of so-called teammates working toward individual goals.

What would be missing, is an underlying business logic that forms the necessary context for understanding everything else.

To become the kind of savvy, motivated, mutually-accountable homebuilding team required to compete effectively today in the business world, everyone on the team has to learn the “business” of homebuilding, they have to understand their individual responsibilities as part of the overall team, and they have to understand what is at stake, individually and collectively.

That is the role of Open-Book Management.

But, it is not enough that teammates understand the business outcome that is at stake;  they must each have a personal stake in that business outcome.

That is the role of performance compensation.

We like the balance between these five Velocity Accelerators®:  a blend of immediate, mid-term, and long-range initiatives that accelerate velocity, but also improve margins.

Come.  Participate.  Learn.

Pipeline Workshops™: What’s your Production IQ®?

Posted August 4, 2018 By Fletcher Groves

The fundamental understanding that emerges from the DuPont identity regarding Return on Assets is this:  remove the financial leverage (equity multiplier) from the formula, and economic return becomes a function of profitability (Return on Sales) and operating efficiency (Asset Turnover).

Economic return is margin x velocity;  it is a co-equal dependency.

Is margin proficiency necessary?  Yes.  Is it sufficient?  No.  Does superior margin hold-forth the possibility of achieving sustainable competitive separation?  Absolutely not.

We’re not alone in this assessment:

“ . . . [asset] turnover is just as important as profit margin.”  Barron’s Accounting Handbook (Siegel, Shim), 1990, 1997, p. 150.

“ . . . [improving] inventory turnover . . . increases asset velocity, one of the most under-appreciated components of making money . . . higher velocity improves productivity and reduces working capital.  It also improves cash flow, the life-blood of any business.”  Execution: The Discipline of Getting Things Done (Bossidy, Charan, 2002, p. 17)

Nevertheless, in the homebuilding industry, action on the velocity side of Return on Assets – without fail – takes a backseat to action on the margin side of ROA.

Pipeline workshops™ are aimed at changing that paradigm.

The motivation to attend a Pipeline workshop™ starts with the willingness to acknowledge and remedy what amounts to a profound lack of knowledge regarding production principles and disciplines.

You heard me right.

In the homebuilding industry, there is a profound absence of knowledge regarding production systems.

Disagree?  Think you already know this stuff?  Really?  Prove it.  You – and your team – take the test.

  1. We say that a homebuilding production system is a pipeline. What determines the size, capacity, length, and cost of the pipe?  What determines flow?
  2. Is even-flow production a mechanism or an outcome?
  3. What is the most operative, useful determination of size for a homebuilding company?  a. revenue   b. number of employees  c. houses under construction  d. annual closings
  4. From an operational perspective, there are three activities that describe “what happens to money” in a homebuilding business.  The terms for those three activities can be used to express and link the formulas for productivity, cycle time, and inventory turn to the equations for Net Income and Return on Assets.  What are the terms?  What do those activities represent?
  5. What type of workflow is homebuilding?  Is it process management, project management, or a combination of both?
  6. True or False:  A production system that balances capacity across the resources that perform the work does a better job of optimizing the utilization of capacity than a production system that does not balance capacity across those resources.
  7. In what three ways will a production system protect itself from variation and uncertainty?
  8. In scheduling a portfolio of jobs, ________ _____ is the algorithm that considers both task dependency and resource contention.
  9. Calculating the cycle time of a production system requires knowledge of what operational measures?  Determining the level of necessary work-in-process requires knowledge of which operational measures?  Estimating the rate of closings requires knowledge of what operational measures?  How are they connected?
  10. True or False:  Building reasonable safety into task durations is not the best way to insure a high percentage of on-time completions.
  11. Which measure of operating performance is the reciprocal of inventory turn?
  12. Lean Production views homebuilding as a build-to-order process.  Which resource does Lean recommend using to set the pace of production?
  13. What is the difference between measured cycle time and calculated cycle time?  What is the best use for each of them?
  14. True or False:  CCPM (Critical Chain Project Management) does not adjust the job schedule to reflect delays.
  15. What three human behaviors consume the time safety built into a job schedule?
  16. How does the matrix for managing starts in a push release system differ from the same matrix in a pull release system?
  17. As a matter of standard deviation, increasing the probability that a task will finish on-time from 50% to 95% will cause the anticipated duration of the task to increase by a factor of how much?  How many standard deviations does this represent?
  18. Is trade partnering a program or a process?
  19. True or False:  The NAHB Chart of Accounts Income Statement enables a builder to calculate both a breakeven point and a breakeven rate.
  20. How does velocity differ from speed?

(the answers are at the bottom of the post)

It’s just a quiz.  Like any quiz, the questions represent a very small portion of the production and business knowledge required to effectively manage homebuilding production, increase operating performance, generate higher Net Income, and improve Return on Assets.

Every homebuilding company has to determine how it will manage production within a specific context, within parameters that include its market, its product mix, its choice of an information/management technology system, its financial situation.

But, the ability to manage production starts with an understanding of the underlying principles and disciplines.

It starts with what you learn in a Pipeline workshop™.
