Rework is Hell

“Software may be eating the world, but rework is choking software”, tweeted John Jeremiah (@j_jeremiah).  To shed more light on what is choking software, new data was released last week in the 2015 State of the Software Supply Chain Report.

In its discussion of application quality and integrity, the report revealed that the average application includes 106 open source components.  It is clear that the use of these components has benefited development tremendously in helping to speed time to market and improve innovation.  While the benefits are undeniable, development teams are also delivering applications that are “insecure by design”.  Of the 106 components per application, the report’s analysis revealed an average of 24 (i.e., 23%) have known critical or severe security vulnerabilities.  Those same apps also showed an average of 9 restrictive license types (e.g., GPL, AGPL, LGPL).

By electively sourcing components with known vulnerabilities and potential license risks, software development teams are building up higher levels of technical and security debt. And in order to reduce some of that debt, unplanned and unscheduled rework is often required.

No Developer Intentionally Uses Bad Parts

I have never met a developer that intentionally wanted to use “bad” components in their applications.  That said, I have also never met a developer that wanted to spend four hours researching the latest versions, open source licenses and known security vulnerabilities for components (including dependencies) they wanted to use in their applications.  While 57% of development organizations have internal policies in place that direct “thou shall not use components with poor quality and integrity”, many have stated that the policies are not followed or are simply not enforced.

The problem is one of volume and velocity, while people clutch to old processes that simply can’t keep pace.  The analysis in the 2015 State of the Software Supply Chain report revealed that billions of open source downloads occurred in 2014, of which 6.2% had known vulnerabilities (1 in 16 downloads).  For some large companies, the volume of downloads exceeded 240,000 — where 15,000 (7.5%) had known security vulnerabilities.  At these volumes, manual processes and paper-based policies to prevent poor quality or risky components from getting into your software have no possibility of keeping pace.  While software development practices aim for higher velocity, through component-based development as well as Agile, continuous and DevOps practices, the processes to keep up with it have not changed enough.

The only way to keep pace with this velocity is through automation.  And if we want to avoid unplanned rework associated with remediating known security vulnerabilities or selecting alternative components with approved license types, automation has to become the norm rather than the exception within development.

At Speed

“If I look at the mass, I will never act. If I look at the one, I will.” — Mother Teresa

Looking at the massive volume and velocity of open source and other artifact consumption can be discouraging and overwhelming. However, the volume and velocity within our software supply chains will not diminish—and without a new approach, the volume of unchecked quality and integrity of parts being consumed will continue to build up as technical debt.

Automation in areas of testing, build, and deployment has provided significant performance benefits. Likewise, investments in software supply chain automation have shown markedly improved efficiency and controlled risk, as the best practices in the 2015 Report illustrate.  Automation can unleash the potential of an organization’s development capacity. Rarely is there such an opportunity to simultaneously increase speed, efficiency, and quality.

In order to improve the quality and integrity of components used in our applications, we need to release our clutch on old practices.  We can further embrace automation across our software supply chains — and improve the quality of our applications — by considering these three steps:

1. Start with creating a software bill of materials for one application.  Visibility into one application can help you better understand your current component usage. A number of free and paid services are available to help you create a software bill of materials within a few minutes. The bill of materials will help you to identify the unique component parts used within your application and the suppliers who contributed them. These reports list all components used, and several services also identify component age, popularity, version numbers, licenses, and known vulnerabilities.

2. Design approval processes to be frictionless, scalable, and automated.  Manual reviews of components and suppliers cannot keep pace with the current volume and velocity of consumption. Your organization must not only define your policies for supplier and part selection but also find practical ways to enforce them without slowing down development or inadvertently encouraging workarounds. Policies must be agile enough to keep pace with modern development. Strive to automate policy enforcement and minimize drag on developers.

3. Enable developer decision support.  Developers are primary consumers of components in software supply chains. They initiate every component request. Help developers by automating the availability of information on component versions, age, popularity, licenses, and known vulnerabilities within their existing development tools so it is easy to pick the best components from the start. By selecting the highest-quality components from the highest-quality suppliers early, you will improve developer productivity and reduce costs.

Here is the complete 2015 State of the Software Supply Chain Report.  I will also be discussing more of the Report findings and best practices on a webinar scheduled for Wednesday, June 24, 12pm ET (register or view it on-demand).
