Why write a command macro? 13/4
Session Links
  • Write a macro to do something you do often
  • Save time and prevent mistakes
  • Modularize knowledge of the technique to save costs
    • With no macro, you must train everyone to perform the needed actions
    • When you train everyone, everyone carries a copy of the technique in their brains
    • If the technique changes, each mental copy must be updated (and stay updated)
    • With a macro, making a change is far easier and more reliable
  • Reduce training for people who use your model
    • Automate a complex or error-prone procedure
    • Reduce the volume of what you must tell people
    • Maintain flexibility of the actual technique employed
  • Capture a complex technique
    • Encapsulate the procedure by writing a command macro to do it
    • The knowledge of what it does is captured in the macro itself

Perhaps an example will drive these points home.

Let’s suppose that you run a venture capital firm. Every month, you collect financial data from all your portfolio companies, and create a high level summary of the condition of your portfolio. Because of the complexity of the process, it’s beyond the capability of your administrative staff, so you assign this task to several staff analysts.

This is a fairly laborious activity, and although analysts are less well-paid than partners, they’re still not cheap. They’re also capable of higher-level work than collating data. So you decide to have each company submit its financial data using a standard template. You then write a command macro for use by your administrative staff. It collates all the templates, computes the indicators that you use internally to monitor your portfolio and the companies themselves, and adds the data to various charts and graphs for presentations.

In effect, the macro lets you shift the work from analysts to administrators. This frees up the analysts to do work that might be higher value to the firm. Moreover, most changes in the collation procedure — such as the introduction of a new ratio indicator — are invisible to the collation macro operator, so no training is required to support this kind of change.

Function Macros

We focus on function macros in this course because they’re more likely than command macros to make a real difference in your facility with constructing models. For instance, when your customer wants to see result streams displayed as [Month1, Month2, Month3, Q1 Total, Month4, Month5, Month6, Q2 Total, …], you probably realize that such a layout makes copy/paste and fill very inconvenient. A macro can provide a simple means of producing the preferred layout from a more easily maintained pure month structure. It’s also easy to construct macros for running sums and running differences. Can you think of other applications for function macros that make your models easier to build and maintain?
