Introduction

Systems demonstrate automated behavior by enabling the business to meet key goals and objectives faster and at scale. Healthy automation enables users to focus on high-value work and reduces time spent on repetitive, manual tasks or complex data entry.

Most often, automation means translating business processes from one form to another: from paper-based form to digital form, from an old system to a new one. With every business process translation comes an opportunity for transformation.

Transformation is not about using new technologies to introduce disruptive and confusing changes for users. Transformation is about creating simpler ways for work to get done, enabling business to grow without friction, and empowering business users to focus more deeply on what really matters to their stakeholders. From an architectural point of view, this involves identifying tasks that can be eliminated altogether, or handled automatically. It requires a clear connection between how technology is used and its measurable impact on the business.

Something important to note about automation with Salesforce: it can be done with a variety of tools, using programmatic and declarative skill sets. Designing automations that are well-architected is not about choosing to build with just one automation tool. It is about using approaches that are consistent and predictable, and enabling teams to develop, test, deploy, and maintain the automations you design. Your automations should take the most maintainable and readable form possible.

This section covers how to design and refactor automations to enable businesses to meet key objectives faster and at scale. To learn more about choosing the right tool for your automation use case, see the Architect’s Decision Guide to Record-Triggered Automation.

You can improve the architecture of your automations in Salesforce by focusing on efficiency and data integrity.

Efficiency

Creating efficiency in your automations isn’t about dutifully re-creating business as usual with Salesforce technologies. It’s about deeply understanding the key metrics and business outcomes that teams will be accountable for meeting or tracking, and stepping back to see functional units within and across the work that you’re automating. It’s about identifying how you can create patterns with your automations that enable the business to operate more effectively and quickly, at scale.

Efficient automation logic will make your systems:

More scalable and valuable for the business
More helpful for users
More adaptable and able to meet evolving business needs

You can improve efficiency in your automations through process design and operational logic.

Process Design

Process design involves defining the ways work gets done. Building truly efficient and effective processes means your designs do not just replicate current ways of working. Identifying and removing ineffective or unclear steps is essential. Optimized processes should create measurable business value (see KPIs) without unnecessary steps. Unclear or unnecessary steps will likely create technical debt and result in unmaintainable automations.

Often, the responsibility for discovering and documenting business processes will fall under the responsibility of a business analyst or even a system administrator. Architects are responsible for partnering with these members of your team to make sure your process designs are technically sound and well structured. Applying your knowledge of the Salesforce platform as early as possible will help your team identify processes to streamline through automation or processes that need to change to avoid costly customizations.

To build optimized processes for Salesforce, consider:

Define processes thoroughly. Processes with unclear purposes or ambiguous definitions are more likely to be misinterpreted at design-time. This will lead to flawed designs that are based on assumptions, which will result in incorrect or inefficient automations. Ensure the business processes you want to automate meet the following standards:
- Scoped to a single, specific function (see Functional Units)
- Has clearly defined, measurable outputs (see Business Value)
- Has clearly defined inputs and outputs
Make process steps clear.* While it can sometimes be tempting to add additional steps that “might be helpful in the future”, this is never a good approach. Every step in an automation be relevant to the outcome of the overall process. Ensure each process step has the following characteristics:
- Performs a specific, granular task (See composable)
- Required for the process to generate its defined output (remove all non-essential steps)
- Can be completed using a minimal number of resources
- Makes use of existing system data instead of asking for user inputs where possible (See engaging)
- Provides input options that users can understand without having to know how the underlying systems work (See helpful)

The list of patterns and anti-patterns below shows what proper (and poor) optimization looks like in a Salesforce org. You can use these to validate your automation designs before you build, or identify automations that need to be optimized further.

To learn more about process automation tools available from Salesforce, see Tools Relevant to Automated.

Operational Logic

Operational logic deals with how effectively a process is translated from its design into an actual implementation. Automations with strong operational logic continue to perform well, regardless of spikes in transaction volumes or the number of concurrent instances that are running. Logically sound automations help businesses to more easily scale to operate at higher levels of demand. Building strong operational logic into your automations is directly related to the overall reliability of your system.

Automations that do not operate effectively provide poor user and customer experiences, leading to both potential revenue losses and loss of customer trust. They also have higher maintenance costs and can become bottlenecks that delay related processes, contributing to overall system performance issues.

To create effective operational logic in automations, consider:

Ensure everyone creating automations knows the right way to do it. Poor design choices can be made with any kind of automation tool. Code is no less prone to errors or poor implementation choices than click-based tools. The use of hard-coded reference IDs, for example, is an anti-pattern that appears in both Flow and code. Click-based tools should not be viewed as a license to allow anyone and everyone to release an automation into production. Every team member who creates an automation needs to know how to build it the right way. See readability and design standards for more about how to define and apply effective standards across your systems.
Clearly document all execution paths. Increased usage of automations does not only increase potential data volumes, it also increases unplanned invocation contexts. You need to understand how different automations can be invoked, and ensure proper transaction controls (see data handling) appear in all automations that have multiple entry points. For example, screen flows won’t run with bulk data loads, but Apex triggers and triggered (and autolaunched) flows probably will. Clearly documenting planned and potential execution paths for automations is a key aspect of understanding what logical conditions you will need to accomodate during implementation.
“Bulkify” all data operations (including SOQL). Every data operation (insert, update, and so on) should be carried out against collections. Always. Without exceptions. This is what is meant by “bulkifying” operations. Though the platform can support singleton data operations, you should never allow singleton patterns to be implemented.
Use SOSL for search operations. There is a misconception that data operations cannot be carried out against records returned via SOSL. It is true that DML cannot be invoked directly against SOSL results, but code can parse SOSL results and create a collection that can be referenced in DML or Database class methods. The key differences between SOSL and SOQL are the return types for each and how they respond to generalized or wildcard searches. SOSL can work against several sObject types (which is why the return type is different) and it can handle wildcard and generalized string searches with better performance than SOQL.
Treat SOQL like a data operation. Don’t use SOQL to find records — use it to refine your data operations. SOQL and data operations can have very similar impact on the performance of the underlying relational database. SOQL can even pass an explicit DML indicator that will lock database rows in anticipation of data operations. To create scalable automations, make sure you treat SOQL with similar due diligence: don’t use it without very specific, well-formed selection criteria, do not allow extraneous field references, and require careful data type matching between fields and filter inputs in WHERE statement logic. Your code should also have proper controls to ensure a query will never run in non-bulkified contexts or against null or blank filter criteria.
Keep synchronous operations strictly focused on work that helps a user in real time. During your process optimization, identify logic that is relevant to what users need done in real time or near real time and what can be deferred into an asynchronous (async) transaction. See Data Handling for more considerations about designing sync/async operations.

The list of patterns and anti-patterns below shows what proper (and poor) operational logic looks like in Salesforce automation. You can use these to validate your automation designs before you build, or identify automations that need to be optimized further.

To learn more about tools available from Salesforce that can help you plan for scale, see Tools Relevant to Automated.

KPIs

Automation KPIs measure the impact of an automation over time. Without them, you’ll have no way to tell if an automation is truly adding business value or creating unintended complexity for your users. Every automation you build should be tied to a clear, measurable set of KPIs.

Good KPIs are defined by a measurable value along with an associated time frame. Examples include:

[X number] working hours saved per month
Processing failures from manual data entry reduced by [Y%] per week

Once you have clear, measurable KPIs, you have to also understand if and how an automation in Salesforce will generate data that is relevant to reporting against those KPIs.

The list of patterns and anti-patterns below shows what proper (and poor) KPIs look like when it comes to Salesforce automations. You can use these to validate your existing KPIs, or identify where you need to better identify KPIs before you build.

Data Integrity

Data integrity is about how well a system maintains accurate and complete data. The Salesforce Platform maintains robust, built-in processing logic designed to protect the integrity of data stored in an individual org’s relational database. One of the fundamentals of building healthy automations is understanding the built-in data integrity behaviors of Salesforce, and making sure all your automation designs align with (and acknowledge) these behaviors.

The biggest anti-patterns in automation design arise from failing to recognize the powerful data integrity services already provided by Salesforce and failing to use standard functionality that takes advantage of these services. To design automations that protect and maintain data integrity you must be familiar with the fundamental order of operation behaviors of Salesforce.

Properly extending data integrity into your custom automations means your system can:

operate against bulk and large data volumes without manual intervention,
enforce user security policies when needed and switch to system context when needed,
encounter errors at run time and follow predictable recovery or failure paths.

You can build better data integrity into your Salesforce automations through proper data handling and error handling.

Data Handling

The first step to designing for proper data handling in Salesforce is understanding how the multitenant platform handles transactions. This includes understanding the built-in order of execution behaviors that the Salesforce Platform uses to ensure data integrity during record-level data operations. For more on the impacts of this behavior, see Database Manipulation in Salesforce Architecture Basics.

Poor data handling in your automations can be some of the most difficult anti-patterns to identify and fully remediate. The recursive and overlapping nature of the platform’s order of execution can make it difficult to see where issues originate. The specific section of code or flow that throws a fatal error or exceeds governor limits may not be the root cause of an underlying data handling issue.

Transaction awareness is key to building automations that perform reliably and at scale with Salesforce. This means making sure that every step in an automation is designed with the knowledge of where it is in relation to the platform-controlled order of execution, can carry out its function correctly, and passes on information to the next step correctly.

Regardless of the automation tool you are using, proper transaction awareness follows similar patterns and requires common considerations:

Assume every automation will be asked to run against large data volumes without notice, at any given time. Automations should have paths to allow for batch or bulk execution (see Scalability).
Do not mix system and user context data operations in the same transaction.
Reserve sync data operations for before contexts and use async operations for all after context actions.
Use messaging and notifications to avoid creating in-app experiences that would require a user to wait for data based on the results of an async operation.

Beyond transaction awareness, there is a second dimension to data handling: knowing when to carry out logic in different execution contexts. Common reasons to break automations up into different execution contexts include:

Large volume and/or complex data operations
- Bulkifying operations does not guarantee an automation will handle large data volumes correctly. If the volume of data operations within in an automation will exceed per transaction limits, you will need to carry out data operations using functionality specific to large data volumes (such as via batch Apex or the Bulk 2.0 API). These have distinct transaction limits, suited to large data volumes.
- Data operations that need to traverse complex relationship hierarchies or carry out complex recalculations (not including formula fields) across records can easily exceed per transaction limits when carried out in bulk. Consider how “noisy” an update to one record is, in terms of the related data operations or SOQL needed to complete subsequent actions in the system.
- The types of sObjects involved in the entire chain of an automation can require you to split data operations into separate transactions to avoid “mixed DML” errors.
Logic that needs to execute in user or system context
- The Salesforce Platform enforces sharing and visibility in user context. If you need to perform operations that extend beyond the permission levels of users of your automation, you’ll have to make sure those operations execute in system context.
- Different tools will or will not run in different contexts:
  - Apex will run in system context by default. You can control if and how Apex behaviors enforce user-level sharing rules by using sharing keywords in an Apex class definition.
  - Flow has no single default behavior. A flow will run in user or system context based on how the flow is launched. You have the option to enforce sharing in system context.
  - Processes (that is, automations built with Process Builder) run in system context without sharing considerations. (Note: We recommend building low-code automations with Flow. See Architect’s Guide to Record-Triggered Automation for more on this.)
Logic that needs to execute asynchronously
- External system operations - Synchronous callouts or actions that access external data aren’t included in any platform rollback behaviors. To take advantage of these behaviors, you must place actions involving external systems into separate transactions (using async Apex methods, asynchronous paths, or invocable actions).
- Eventing and messaging - To control the flow of events or messages related to data operations (and take advantage of platform rollback behaviors), place all actions related to messaging or events in after contexts, using async Apex methods.

The list of patterns and anti-patterns below shows what proper (and poor) data handling looks like in Salesforce automations. You can use these to validate your automation designs before you build, or identify automations that need to be refactored to improve data handling.

To learn more about tools available from Salesforce for data handling in automation, see Tools Relevant to Automated.

Error Handling

Error handling is critical for data integrity. Strong error handling also helps your system scale and age with more resilience.

Improper error handling in automations can lead to:

Record inconsistencies and other data integrity issues
Sending inaccurate notifications to users and other systems
Wasting time and resources on manual or repeated processing
Overall lack of trust in a system

Error handling in automations requires giving any running process the capability to parse an error for information, access logic about what the next steps should be based on error information, and then follow the correct path. These capabilities don’t need to be built over and over in every automation (that’s an optimization anti-pattern). Instead, every automation in the system should have the ability to connect to the relevant error handling components.

To build proper error handling controls into your automations, ask these questions:

What is a “fatal” error?
What is a “recoverable” error?
For automations triggered by user actions, how can the automation catch and notify the user of errors before attempting to commit changes?

Once you’ve decided how to handle these errors, you can start to build effective error handling into your automations. The list of patterns and anti-patterns below shows what proper (and poor) error handling looks like in a Salesforce automation. You can use these to validate your automation designs before you build, or identify automations that need to be refactored to improve error handling.

Business Value

The concept of business value, in the context of automation, is about how well processes create measurable, positive impact for business stakeholders. Ideally, process automation enables users to spend less time on repetitive, low-value tasks. It also helps boost data integrity by eliminating manual processing activities that could introduce errors. Much like Process Design, identifying and delivering automations that will drive real business value requires work beyond basic discovery and business analysis.

At times, it may seem like the best way to deliver value to the business is to simply automate every process requested by a business user, either in the order they appear in your backlog (or ticketing queue) or based on political factors in your organization. This can lead to two related problems: building automations in a suboptimal order and building the wrong automations altogether. The first problem, poor prioritization, prevents high-value processes from getting implemented when they should, potentially slowing growth. The second problem, building the wrong automations, not only delays the delivery of high-value automations, it also leads to misspent time, unnecessary costs, and increased frustration among delivery teams.

You can deliver greater business value by focusing on KPIs and prioritization.
